Subject: ath10k: fix debugfs pktlog_filter write

From: Anilkumar Kolli <akolli@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.
