wifi: rtw89: debug: Fix error handling in rtw89_debug_priv_btc_manual_set()

Browse source 
[ Upstream commit 59b4cc439f ]

If there is a failure during kstrtobool_from_user()
rtw89_debug_priv_btc_manual_set should return a negative error code
instead of returning the count directly.

Fix this bug by returning an error code instead of a count after
a failed call of the function "kstrtobool_from_user". Moreover
I omitted the label "out" with this source code correction.
