Due to a rebase damage, we lost the rtnl_lock() when the patch was
sent out. This causes an RTNL imbalance and failed assertions, due to
missing RTNL protection, for instance:
RTNL: assertion failed at net/wireless/reg.c (4025)
WARNING: CPU: 60 PID: 1720 at net/wireless/reg.c:4025 regulatory_set_wiphy_regd_sync+0x7f/0x90 [cfg80211]
Call Trace:
iwl_mvm_init_mcc+0x170/0x190 [iwlmvm]
iwl_op_mode_mvm_start+0x824/0xa60 [iwlmvm]
iwl_opmode_register+0xd0/0x130 [iwlwifi]
init_module+0x23/0x1000 [iwlmvm]
Fix this by adding the missing rtnl_lock() back to the code.
Fixes: eb09ae93da ("iwlwifi: mvm: load regdomain at INIT stage")
