[PATCH v2] wifi: rtw89: debug: fix error code in rtw89_debug_priv_btc_manual_set

[Zhang Shurong]

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 by returning the correct error code.
