[PATCH] ublk_drv: fix double shift bug

[Dan Carpenter <dan.carpenter@oracle.com>]

The test/clear_bit() functions take a bit number, but this code is
passing as shifted value.  It's the equivalent of saying BIT(BIT(0))
instead of just BIT(0).

This doesn't affect runtime because numbers are small and it's done
consistently.
