Always set resulting errno on failure of chmod() functions family.
Always set resulting errno on failure of chmod() functions family.

The value pointed by result_errno_ptr argument is supposed to set
to errno value returned by real syscall in case of its failure
by vperm_chmod_done_update_state() function,
but it was set not in all cases.
This change fixes this bug.
