wcn36xx: Fix error handling path in 'wcn36xx_probe()'

Browse Source 
[ Upstream commit a86308fc53 ]

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: 5052de8def ("soc: qcom: smd: Transition client drivers from smd to rpmsg")
