crypto: hisilicon/qm - fix incorrect judgment in qm_get_complete_eqe_num()

Browse source 
In qm_get_complete_eqe_num(), the function entry has already
checked whether the interrupt is valid, so the interrupt event
can be processed directly. Currently, the interrupt valid bit is
being checked again redundantly, and no interrupt processing is
performed. Therefore, the loop condition should be modified to
directly process the interrupt event, and use do while instead of
the current while loop, because the condition is always satisfied
on the first iteration.
