nfs : set ctx for every inode looked up nfs3_fh_resolve_inode_lookup_cbk()
The inode ctx for nfs xlator is set with help nfs_fix_generation. But currently gnfs is crashing because inode_ctx is becoming null nfs3_resolve_inode_hard() is used to perform a lookup on entire path and looks like function is missing to set the ctx for inode. This patch will set ctx for the inode which it looked on. Change-Id: I464fa7f78df1bae990ebe97de8ccf6d5fb74fc9f fixes: bz#1651439 Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com>
