staging: wilc1000: avoid NULL pointer dereference on error
The host_int_init() function can dereference the pstrWFIDrv pointer while it is NULL on its error path. Jump directly to the _fail_ error label in the end of the error handling path to avoid that. By doing that we also skip stopping our kthread and destroying our message queue, but they were not started or created yet in that case anyway. This fixes the following coccinelle error: drivers/staging/wilc1000/host_interface.c:6100:17-33: ERROR: pstrWFIDrv is NULL but dereferenced.
