3.19.8-ckt23 -stable review patch.  If anyone has any objections, please let me 
know.

---8<------------------------------------------------------------

From: Anilkumar Kolli <ako...@qti.qualcomm.com>

commit 9ddc486aa09a3413a6c492fcf160ce61bfccb7b1 upstream.

It is observed that, we are disabling the packet log if we write same
value to the pktlog_filter for the second time. Always enable pktlogs
on non zero filter.

Fixes: 90174455ae05 ("ath10k: add support to configure pktlog filter")
