ap: verify ATTR_MAC exists in NEW_STATION

Browse Source 
Caught by static analysis, if ATTR_MAC was not in the message there
would be a memcpy with uninitialized bytes. In addition there is no
reason to memcpy twice. Instead 'mac' can be a const pointer which
both verifies it exists and removes the need for a second memcpy.
