Bluetooth: btrtl: Prevent potential NULL dereference
The btrtl_initialize() function checks that rtl_load_file() either
had an error or it loaded a zero length file. However, if it loaded
a zero length file then the error code is not set correctly. It
results in an error pointer vs NULL bug, followed by a NULL pointer
dereference. This was detected by Smatch:
drivers/bluetooth/btrtl.c:592 btrtl_initialize() warn: passing zero to 'ERR_PTR'
Fixes: 26503ad25de8 ("Bluetooth: btrtl: split the device initialization into smaller parts")
