Subject: [PATCH 4.19 147/190] staging: wilc1000: fix error path cleanup in wilc_wlan_initialize()

[ Upstream commit 6419f818ababebc1116fb2d0e220bd4fe835d0e3 ]

For the error path in wilc_wlan_initialize(), the resources are not
cleanup in the correct order. Reverted the previous changes and use the
correct order to free during error condition.
