[PATCH] wcn36xx: Fix error handling path in 'wcn36xx_probe()'

[Christophe JAILLET]

In case of error, 'qcom_wcnss_open_channel()' must be undone by a call to
'rpmsg_destroy_ept()', as already done in the remove function.

Fixes: 5052de8deff5 ("soc: qcom: smd: Transition client drivers from smd to rpmsg")

Not 100% sure of the commit for Fixes, but it is consistent with the
analysis in efad8396e906 where the same call has been added in the remove
function.
