[PATCH] hidp: Ensure the session is marked as terminating to enable other functions to abort early.

[Karl Relton <karllinuxtest.relton@ntlworld.com>]

From: Karl Relton <karllinuxtest.relton@ntlworld.com>

Ensure the session is marked as terminating no matter how hidp_session
drops out of its main loop.

This enables other functions (such as hidp_get_raw_report) to
abort early once a session is in its closing
stages - important since the cleanup of a session will remove
input/hid devices which (via the power_supply code) will typically
trigger a call to hidp_get_raw_report for an ill-fated attempt to
get the battery status. Without this change hidp_get_raw_report
can end up stalling the cleanup process for its 5 second timeout.
