ath10k: implement prb tmpl wmi command

New firmware revisions with beacon templates need
probe templates as well because they don't forward

This is required for new firmware to work with

When replenishing Rx buffers driver updates the address of the
buffer and the index of rx buffer in rx ring to the firmware.
Change in order by CPU can cause rx ring corruption. Add memory

when a short command response is received without a key length
causing non initialised memory to be interpreted as the key
length resulting in a memcpy() overwriting the part of the

For v1 key material API firmwares, there is no need to send
command to delete WEP key. WEP encryption/decryption is controlled
by mac_control command.
