File open/set_maseter ioctl and file close/drop_master ioctl share the same master handling code. Extract it.

Note that vmwgfx's master_set callback needs to know whether the master is a new one or has been used already, so thread this through. On the close/drop side a similar parameter existed, but wasnt used. Drop it to simplify the flow.
