firmware: qcom_scm: Fix error retval in __qcom_scm_is_call_available()

Browse Source 
[ Upstream commit 38212b2a8a6fc4c3a6fa99d7445b833bedc9a67c ]

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")
