wcn36xx: Fix error handling path in 'wcn36xx_probe()'
[ Upstream commit a86308fc534edeceaf64670c691e17485436a4f4 ]
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")
