Dan Carpenter d844181869 Bluetooth: btrtl: Prevent potential NULL dereference 
[ Upstream commit 324dddea32 ]

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: 26503ad25d ("Bluetooth: btrtl: split the device initialization into smaller parts")
