Simplify exec_permission_lite(), part 3



Don't call down to the generic inode_permission() function just to
call the inode-specific permission function - just do it directly.

The generic inode_permission() code does things like checking MAY_WRITE
and devcgroup_inode_permission(), neither of which are relevant for the
light pathname walk permission checks (we always do just MAY_EXEC, and
the inode is never a special device).
