If there is a failure during kstrtobool_from_user()
rtw89_debug_priv_btc_manual_set should return negative error code
instead of returning the count driectly.
Fix this bug with the following changes:
- Return an error code instead of a count after a failed call
of the function "kstrtobool_from_user".
- Omit the label "out" with this source code correction.
