    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’
