rpmsg: glink: Free pending deferred work on remove
commit 278bcb7300f61785dba63840bd2a8cf79f14554c upstream.
By just cancelling the deferred rx worker during GLINK instance teardown
any pending deferred commands are leaked, so free them.
Fixes: b4f8e52b89f6 ("rpmsg: Introduce Qualcomm RPM glink driver")
