Thomas Hellstrom 7150da7c28 drm: Fix an unwanted master inheritance v2 
commit a0af2e538c upstream.

A client calling drmSetMaster() using a file descriptor that was opened
when another client was master would inherit the latter client's master
object and all its authenticated clients.

This is unwanted behaviour, and when this happens, instead allocate a
brand new master object for the client calling drmSetMaster().

Fixes a BUG() throw in vmw_master_set().

[ luis: backported to 3.16:
  - drm_setmaster_ioctl() in file drm_stub.c instead of drm_drv.c
  - adjusted context ]
