Subject: [PATCH v2 4/5] toshiba_acpi: Remove TOS_FAILURE check from some functions

This patch removes the check for TOS_FAILURE whenever we are using
the tci_raw function call, as that code is only returned by the
{hci, sci}_{read, write} functions and never by the tci_raw, and
thus making that check irrelevant.
