wlcore: send EAPOL frames with voice priority

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Send EAPOL frames with voice priority by setting (the new)
TX_HW_ATTR_EAPOL_FRAME bit in tx attribute.

Sending EAPOL with voice priority fixes re-key
timeout issues during heavy traffic.
