Fix inst_num overflow in qat_crypt.c
This patch fixes the same issue which was previously addressed in
6051.  The variable "inst_num" was of the incorrect type and
"atomic_inc_32_nv()" could cause an overflow damaging its neighbor.

Cast the return value of atomic_inc_32_nv() to Cpa32U.

Fix a few types for num_inst for clarity.
