serial: 8250_port: Remove redundant pm_runtime_mark_last_busy() call

Browse Source 
The pm_runtime_mark_last_busy() call is redundant in the wrapper function
as pm_runtime_put_autosuspend() already calls pm_runtime_mark_last_busy()
internally to update the last access time of the device before queuing
autosuspend.
