Subject: [PATCH] ath10k: fix debugfs pktlog_filter write

From: Anilkumar Kolli <[email protected]>

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")

This is not the correct way to submit patches for inclusion in the
stable kernel tree. Please read Documentation/stable_kernel_rules.txt
