vgaarb: fix signal handling in vga_get()

commit 9f5bd30818c42c6c36a51f93b4df75a2ea2bd85e upstream.

There are few defects in vga_get() related to signal hadning:

  - we shouldn't check for pending signals for TASK_UNINTERRUPTIBLE
    case;

  - if we found pending signal we must remove ourself from wait queue
    and change task state back to running;

  - -ERESTARTSYS is more appropriate, I guess.
