firmware: qcom_scm: Fix error retval in __qcom_scm_is_call_available()
Since __qcom_scm_is_call_available() returns bool, have it return false
instead of -EINVAL if an invalid SMC convention is detected.
This fixes the Smatch static checker warning:
drivers/firmware/qcom_scm.c:255 __qcom_scm_is_call_available()
warn: signedness bug returning '(-22)'
Fixes: 9d11af8b06a8 ("firmware: qcom_scm: Make __qcom_scm_is_call_available() return bool")
