wifi: iwlwifi: Fix memory leak in iwl_mvm_init()

Browse source 
[ Upstream commit ed2e916c890944633d6826dce267579334f63ea5 ]

When iwl_opmode_register() fails, it does not unregster rate control,
which will cause a memory leak issue, this patch fixes it.

Fixes: 9f66a397c8 ("iwlwifi: mvm: rs: add ops for the new rate scaling in the FW")
