[PATCH -next] capability: Add parameter description in kernel-doc comment

[Yang Li]

Add the description of @mnt_userns in privileged_wrt_inode_uidgid()
and capable_wrt_inode_uidgid() kernel-doc comment to remove warnings
found by running scripts/kernel-doc, which is caused by using 'make W=1'.

kernel/capability.c:491: warning: Function parameter or member
'mnt_userns' not described in 'privileged_wrt_inode_uidgid'
kernel/capability.c:507: warning: Function parameter or member
'mnt_userns' not described in 'capable_wrt_inode_uidgid'
