xlators/cluster/afr/src/afr-self-heal-common.c: remove unneeded memset()

Since we are going over the whole array anyway, initialize it
properly, to either 1 or 0.

Only compile-tested!

xlators/mgmt/glusterd/src/glusterd-geo-rep.c: read() in 4K blocks

The current 1K seems small. 4K is usually better (in Linux).

Also remove a memset() that I don't think is needed between reads.

Only compile-tested!

xlators/storage/posix/src/posix-{gfid-path|inode-fd-ops}.c: remove memset()
before sys_*xattr() functions.

I don't see a reason to memset the array sent to the functions
sys_llistxattr(), sys_lgetxattr(), sys_lgetxattr(), sys_flistxattr(),
sys_fgetxattr().

(Note: it's unclear to me why we are calling sys_*txattr() functions with
XATTR_VAL_BUF_SIZE-1 size instead of XATTR_VAL_BUF_SIZE ).

Only compile-tested!
