iwlwifi: mvm: bail out if CTDP start operation fails
We were assigning the return value of iwl_mvm_ctdp_command() to a variable, but never checking it. If this command fails, we should not allow the interface up process to proceed, since it is potentially dangerous to ignore thermal management requirements. Fixes: commit 5c89e7bc ("iwlwifi: mvm: add registration to cooling device") Signed-off-by: NLuca Coelho <luciano.coelho@intel.com>
