remoteproc: fix memory leak of remoteproc ida cache layers 

The remoteproc core uses a static ida named rproc_dev_index for
assigning an automatic index number to a registered remoteproc.
The ida core may allocate some internal idr cache layers and ida
bitmap upon any ida allocation, and all these layers are truely
freed only upon the ida destruction. The rproc_dev_index ida is
not destroyed at present, leading to a memory leak when using the
remoteproc core as a module and atleast one rproc device is
registered and unregistered.

Fix this by invoking ida_destroy() in the remoteproc core module
exit.
