omap: remoteproc: return rproc status instead of omap device status

rproc_get_state was returning omap_device status instead of
the current rproc status. This mismatch was leading to some
unhandled states like when the remote proc is hibernated. This
was causing users-space registration for PROC_START events to
timeout, due to the mismatch states.
