Subject: [PATCH] Bluetooth: qca: fix firmware check error path

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.
