[PATCH v1 2/6] baseband/acc: fix to possible overflow

[Nicolas Chautru]

Potential overflow issue when casting to 64bits,
notably relevant when extending number of queues.

Coverity issue: 381665
Fixes: 32e8b7ea35 ("baseband/acc100: refactor to segregate common code")
Fixes: 40e3adbdd3 ("baseband/acc200: add queue configuration")
