glusterd/cli: coverity fixes
A downstream coverity run has revealed few of the following coverity defects. Since the downstream code is a clone of a specific upstream branch the defects hold true for the upstream as well. Defect type: NEGATIVE_RETURNS xlators/mgmt/glusterd/src/glusterd-rpc-ops.c:641: negative_returns: "op_errno" is passed to a parameter that cannot be negative. Defect type: BUFFER_SIZE_WARNING xlators/mgmt/glusterd/src/glusterd-volume-ops.c:2124: buffer_size_warning: Calling strncpy with a maximum size argument of 261 bytes on destination array "volinfo->volname" of size 261 bytes might leave the destination string unterminated. Defect type: BUFFER_SIZE_WARNING xlators/mgmt/glusterd/src/glusterd-volgen.c:4888: buffer_size_warning: Calling strncpy with a maximum size argument of 261 bytes on destination array "volinfo->volname" of size 261 bytes might leave the destination string unterminated. Defect type: STRING_OVERFLOW xlators/mgmt/glusterd/src/glusterd-volgen.c:3449: string_overflow: You might overrun the 256 byte destination string "tmp_volname" by writing 261 bytes from "volinfo->volname". Defect type: BUFFER_SIZE_WARNING xlators/mgmt/glusterd/src/glusterd-utils.c:3392: buffer_size_warning: Calling strncpy with a maximum size argument of 261 bytes on destination array "new_volinfo->volname" of size 261 bytes might leave the destination string unterminated. Defect type: NO_EFFECT xlators/mgmt/glusterd/src/glusterd-utils.c:7359: remediation: Was "rebal->rebalance_id" formerly declared as a pointer? Defect type: USE_AFTER_FREE xlators/mgmt/glusterd/src/glusterd-utils.c:7115: pass_freed_arg: Passing freed pointer "volinfo" as an argument to "glusterd_friend_contains_vol_bricks". Defect type: DEADCODE cli/src/cli-cmd-parser.c:1767: dead_error_begin: Execution cannot reach this statement: "ret = -1;".
