platform/x86: intel_scu_ipc: Fix busy loop expiry time

Browse source 
commit 41512e4dc0 upstream.

The macro IPC_TIMEOUT is already in jiffies (it is also used like that
elsewhere in the file when calling wait_for_completion_timeout()). Don’t
convert it using helper functions for the purposes of calculating the
busy loop expiry time.
