qcacmn: Fix Runtime PM resume issue for ipci interface

For ipci interface platforms, currently RTPM resume is
requested from CE interrupt handler even when suspend
is in progress. But ideally we should request resume
only RTPM state is in suspended, since as part of suspend
sequence also we will get CE WOW events and this should
not trigger resume.

Fix this by requesting resume from CE interrupt handler
only when driver state is suspended.
