rpmsg: smd: do not use mananged resources for endpoints and channels
All the managed resources would be freed by the time release function
is invoked. Handling such memory in qcom_smd_edge_release() would do
bad things.
Found this issue while testing Audio usecase where the dsp is started up
and shutdown in a loop.
This patch fixes this issue by using simple kzalloc for allocating
channel->name and channel which is then freed in qcom_smd_edge_release().
Without this patch restarting a remoteproc would crash the system.
