iwlwifi: mvm: generalize the other-scan stopping code
Instead of hardcoding the differences between UMAC scans and LMAC
scans (which in this case is the number of simultaneous scans that can
run), introduce a max_scans variable and stop scans of the other type
(i.e. stop sched scan if regular scan is being attempted and
vice-versa) if the number of running scans reached the maximum.
Add a function that checks if the maximum number of scans was reached
and stops the appropriate scan to make room for the new scan.
