features/shard: Fix crash and test case in RENAME fop
Setting the refresh flag in inode ctx in shard_rename_src_cbk()
is applicable only when the dst file exists and is sharded and
has a hard link > 1 at the time of rename.
But this piece of code is exercised even when dst doesn't exist.
In this case, the mount crashes because local->int_inodelk.loc.inode
is NULL.
