Fix MBOX_C_RESET_STATE command crash

Currently MBOX_C_RESET_STATE tries to access
context->fds[LPC_CTRL_FD].fd but it's set to a negative value to avoid
being part of the poll loop.  This causes MBOX_C_RESET_STATE command
crashes with:

  [MBOXD 1479755597.524480127] Couldn't MAP the host LPC bus to the platform flash
  [MBOXD 1479755597.524710309] Couldn't point the LPC BUS back to actual flash
  [MBOXD 1479755597.525068895] Error handling MBOX event: Bad file descriptor

This patches removes the negative FDs and setups up a polls FD number
for the number of FDs to poll.
