PCI/VGA: Pass vga_get_uninterruptible() errors to userspace
If VGA routing cannot be established, vga_get_uninterruptible() returns an
error and does not increment the lock count. Return the error to the
caller.
Return before incrementing uc->io_cnt/mem_cnt so vga_arb_release() won't
call vga_put() when userspace closes the handle.
