storage/posix: perform chmod after chown.

Problem:
When a replica brick is added to a volume, set-user-ID and set-group-ID
permission bits of files are not set correctly in the new brick. The issue
is in the posix_setattr() call where we do a chmod followed by a chown.

But according to the man pages for chown:
When the owner or group of an executable file are changed by an unprivileged
user the S_ISUID and S_ISGID mode bits are cleared.  POSIX does not specify
whether this also  should  happen  when  root does the chown().

Fix:
Swap the chmod and chown calls in posix_setattr()
