HID: intel-ish-ipc: Reset clients state on resume from D3

When ISH resumes from D3, the connection between ishtp clients and firmware
is lost. The ish_resume() function schedules resume_work asynchronously to
re-initiate the connection and then returns immediately. This can cause a
race where the upper-layer ishtp client driver's .resume() may execute
before the connection is fully restored, leaving the client in a stale
connected state. If the client sends messages during this window, the
firmware cannot respond.

To avoid this, reset the ishtp clients' state before returning from
ish_resume() if ISH is resuming from D3.
