Subject: [PATCH] iwlwifi: mvm: assign SAR table revision to the command later
Git-commit: 28db1862067cb09ebfdccfbc129a52c6fdb4c4d7
Patch-mainline: v5.12-rc1
References: bsc#1187495

The call to iwl_sar_geo_init() was moved to the end of the
iwl_mvm_sar_geo_init() function, after the table revision is assigned
to the FW command.  But the revision is only known after
iwl_sar_geo_init() is called, so we were always assigning zero to it.

Fix that by moving the assignment code after the iwl_sar_geo_init()
function is called.
