[PATCH 38/42] iwlwifi: mvm: rename generic_scan_cmd functions to dwell

[Emmanuel Grumbach <emmanuel.grumbach@intel.com>]

From: Luciano Coelho <luciano.coelho@intel.com>

The generic scan command functions are now irrelevant, since both
sched and regular scans are in the same code.  So rename this
functions to dwell and isolate all the dwell-related setting to them.
Keeping the dwell code separate makes it easier to compare the LMAC
and UMAC versions.
