block: change wait on bd_claiming to use a var_waitqueue
bd_prepare_to_claim() waits for a var to change, not for a bit to be
cleared. Change from bit_waitqueue() to __var_waitqueue() and
correspondingly use wake_up_var(). This will allow a future patch which
change the "bit" function to expect an "unsigned long *" instead of
"void *".
