Shawn Nematbakhsh 4a72f8f607 npcx: shi: Improve host command handling reliability
- Pass-thru to IBF handler code in case both IBHF and IBF interrupts are
  pending, in order to properly keep track our Tx byte count.
- Don't disable the SHI IRQ in our host command handler callback since
  system-wide interrupts are already disabled.

BUG=chrome-os-partner:55711,chrome-os-partner:55721
BRANCH=None
TEST=Manual on gru with subsequent commit. Verify `flashrom -p ec -r
file.bin` passes 100x with no errors or warnings.
