SPM: backend_ipc: Remove unnecessary FIH guard for checks in ipc_schedule

A previous patch 835b161d2 introduced additional checks for the
context. Those have been placed within a TFM_FIH_PROFILE_ON block,
but they do not rely on any FIH functionality.

Thus, remove the guard and always perform the additional scheduling
checks.
