mac80211: fix and optimize MCS mask handling
Currently the code always copies the configured MCS mask (even if it is set to default), but only uses it if legacy rates were also masked out. Fix this by adding a flag that tracks whether the configured MCS mask is set to default or not. Optimize the code further by storing a pointer to the configured rate mask in txrc instead of using memcpy.
