update to latest patch to avoid stability issues in device release path

Changes in v3:

Fixed fastrpc_user_put()/fastrpc_channel_ctx_put() call order in
fastrpc_context_free() and the err_idr path of fastrpc_context_alloc();
the correct ordering from v1 was accidentally reversed in v2
Link to v2: https://lore.kernel.org/all/20260427074021.3774769-1-anandu.e@oss.qualcomm.com/
Changes in v2:
Rewrote commit message to establish the problem first per review
feedback; identified all three UAF dereference sites explicitly
Moved resource cleanup (pending contexts, maps, mmaps) into
fastrpc_user_free() so teardown is consolidated in the kref
release callback
Link to v1: https://lore.kernel.org/all/20260226151121.818852-1-anandu.e@oss.qualcomm.com/

Update the code with new version of the the patch to
avoid stability issues in device release path.
