![]() Building with -Warray-bounds showed a stack variable array index
overflow. Increase the expected size of the array to avoid the warning:

This is justified because the mask size (eng_grps->engs_num) can be at
most 144 (OTX2_CPT_MAX_ENGINES bits), which is larger than available
storage. 4 * 32 == 128, so this must be 5: 5 * 32bit = 160.
Additionally clear the mask before conversion so trailing bits are zero.
