Johan Hovold 7bcba557d5 Bluetooth: qca: fix firmware check error path
commit 40d442f969fb1e871da6fca73d3f8aef1f888558 upstream.

A recent commit fixed the code that parses the firmware files before
downloading them to the controller but introduced a memory leak in case
the sanity checks ever fail.

Make sure to free the firmware buffer before returning on errors.
