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.
Fixes: f905ae0be4b7 ("Bluetooth: qca: add missing firmware sanity checks")
