qcacmn: Send get_station and ll_stats req in a single command

Browse Source 
Currently ll_stats and get_station requests are sent back to back
from user space. The firmware time difference between these two commands
results in extra sleep and wakeup for Q6.

To avoid this extra Q6 sleep and wake, send both requests in a single
command from the driver if the firmware supports that operation. Cache
the get_station results in the driver until user space request reach
to the driver.
