lib: sbi_hart: Do not call delegate_traps() in the resume flow

Browse Source 
The only purpose of this function is to program the initial values of
mideleg and medeleg. However, both of these CSRs are now saved/restored
across non-retentive suspend, so the values from this function are
always overwritten by the restored values.
