remoteproc/omap: fix auto-suspend failure warning during crashed state

The runtime autosuspend on a OMAP remoteproc device is attempted when
the suspend timer expires (autosuspend delay elapsed since the last
time the device is busy). This is the normal autosuspend scenario
for a device functioning normally. This timer can also expire during
the debugging of a remoteproc crash when the remoteproc recovery is
disabled. This is an invalid pre-condition though, so check for the
RPROC_CRASHED state and bail out before the actual check for the
RPROC_RUNNING state. The auto-suspend is also not re-attempted until
the remoteproc is recovered and restored to normal functional state.
