[PATCH 5/5] misc: fastrpc: fix memory leak in fastrpc_channel_ctx_free

[srini]

From: Eddie Lin <eddie.lin@xxxxxxxxxxxxxxxx>

The 'ctx_idr' is initialized but never destroyed when
the channel context is freed, leading to a memory leak.
Add idr_destroy() to properly clean up the IDR resources.

Fixes: f6f9279f2bf0 ("misc: fastrpc: Add Qualcomm fastrpc basic driver model")
