iwlwifi: mvm: use IWL_HCMD_NOCOPY for MCAST_FILTER_CMD
commit 97bce57bd7f96e1218751996f549a6e61f18cc8c upstream.
The MCAST_FILTER_CMD can get quite large when we have many mcast
addresses to set (we support up to 255). So the command should be
send as NOCOPY to prevent a warning caused by too-long commands:
WARNING: CPU: 0 PID: 9700 at /root/iwlwifi/stack-dev/drivers/net/wireless/intel/iwlwifi/pcie/tx.c:1550 iwl_pcie_enqueue_hcmd+0x8c7/0xb40 [iwlwifi]
Command MCAST_FILTER_CMD (0x1d0) is too large (328 bytes)
