Connor Abbott f5af19889f Bluetooth: btqca: Don't modify firmware contents in-place 
commit b43ca511178ed0ab6fd2405df28cf9e100273020 upstream.

struct firmware::data is marked const, and when the firmware is
compressed with xz (default at least with Fedora) it's mapped read-only
which results in a crash:

This also seems to fix a failure to suspend due to the firmware
download on bootup getting interrupted by the crash:

Bluetooth: hci0: SSR or FW download time out
PM: dpm_run_callback(): acpi_subsys_suspend+0x0/0x60 returns -110
PM: Device serial0-0 failed to suspend: error -110
PM: Some devices failed to suspend, or early wake event detected
