Colin Ian King 76ba89c76f commoncap: move assignment of fs_ns to avoid null pointer dereference 
The pointer fs_ns is assigned from inode->i_ib->s_user_ns before
a null pointer check on inode, hence if inode is actually null we
will get a null pointer dereference on this assignment. Fix this
by only dereferencing inode after the null pointer check on
inode.

Detected by CoverityScan CID#1455328 ("Dereference before null check")

Fixes: 8db6c34f1d ("Introduce v3 namespaced file capabilities")
