posix: honour fsync flags in posix_do_zerofill
Backport of http://review.gluster.org/#/c/15100/
commit fe1054110ac54750ca0333a727d83b14a98e165e introduced fallocate +
FALLOC_FL_ZERO_RANGE to do posix_do_zerofill but did not do an fsync if
O_SYNC or O_DSYNC fd flags were set. Prashant Pai pointed out performing
fallocate(2) does not remove the necessity to do fsyncs if durability is
desired: http://linux-fsdevel.vger.kernel.narkive.com/bDmrAUlh/fallocate-falloc-fl-punch-hole
So fixed it to honour the fd flags.
