core: fix Ubuntu code audit (cppcheck) results
See http://review.gluster.org/#/c/7583/ BZ 1086460
AFAICT these are false positives:
[geo-replication/src/gsyncd.c:99]: (error) Memory leak: str
[geo-replication/src/gsyncd.c:395]: (error) Memory leak: argv
[xlators/nfs/server/src/nlm4.c:1200]: (error) Possible null pointer dereference: fde
Program exits, resource leak not an issue
[extras/geo-rep/gsync-sync-gfid.c:105]: (error) Resource leak: fp
Test program:
[extras/test/test-ffop.c:27]: (error) Buffer overrun possible for long command line arguments.
Not built:
[xlators/cluster/ha/src/ha.c:2699]: (error) Possible null pointer dereference: priv
The remainder are fixed with this change-set:

[xlators/performance/quick-read/src/quick-read.c:585]: (error) Possible null pointer dereference: iobuf
Rerunning cppcheck afterwards:
As before, test program:
[extras/test/test-ffop.c:27]: (error) Buffer overrun possible for long command line arguments.
As before, believed to be false positive:
[geo-replication/src/gsyncd.c:99]: (error) Memory leak: str
[geo-replication/src/gsyncd.c:395]: (error) Memory leak: argv
[xlators/nfs/server/src/nlm4.c:1200]: (error) Possible null pointer dereference: fde
As before, not built:
[xlators/cluster/ha/src/ha.c:2699]: (error) Possible null pointer dereference: priv
False positive after fix:
[heal/src/glfs-heal.c:356]: (error) Possible null pointer dereference: remote_subvol
[xlators/cluster/stripe/src/stripe.c:4963]: (error) Possible null pointer dereference: local
