drm/vmwgfx: Fix error printout on signals pending
commit e338c4c2 upstream. The function vmw_master_check() might return -ERESTARTSYS if there is a signal pending, indicating that the IOCTL should be rerun, potentially from user-space. At that point we shouldn't print out an error message since that is not an error condition. In short, avoid bloating the kernel log when a process refuses to die on SIGTERM.
