Introduce the same mutex-wise fix in r227758 for sx locks.

The functions that offer file and line specifications are:
- sx_assert_
- sx_downgrade_
- sx_slock_
- sx_slock_sig_
- sx_sunlock_
- sx_try_slock_
- sx_try_xlock_
- sx_try_upgrade_
- sx_unlock_
- sx_xlock_
- sx_xlock_sig_
- sx_xunlock_

Now vm_map locking is fully converted and can avoid to know specifics
about locking procedures.
