glusterd: avoid buffer overrun for over-long volname

[in glusterd_store_is_valid_brickpath]
When strlen(volname) is no smaller than sizeof(volinfo->volname),
volinfo->volname would end up not being NUL-terminated.
Then, a use of that buffer that expects it to be NUL-terminated
(i.e., glusterd_store_brickinfopath_set's GLUSTERD_GET_BRICK_DIR)
will access beyond the end of the buffer.
Instead, diagnose the too-long volume name and fail.
