crypto: hisilicon/qm - fix the type value of aeq
The type of aeq has only 4bits in dw0 17 to 20bits, but 15bits(17 to
31bits) are read in function qm_aeq_thread(). The remaining 11bits(21
to 31bits) are reserved for aeq, but may not be 0. To avoid getting
incorrect value of type, other bits are cleared.
