qcacmn: Increase timeout from 30s to 60s for freeing tx desc

Browse Source 
Tx completions can be received after 30seconds, this is causing
race condition as there is a forceful freeing of tx descriptors
after 30seconds. This race condition corrupted tx desc pool's
freelist pointer which contains list of all free tx descriptors.
Increasing the threshold from 30seconds to 60seconds. Display
id for which tx descriptor is freed.
