can: etas_es58x: Fix missing null check on netdev pointer

Browse source 
There is an assignment to *netdev that is that can potentially be null
but the null check is checking netdev and not *netdev as intended. Fix
this by adding in the missing * operator.

Fixes: 8537257874 ("can: etas_es58x: add core support for ETAS ES58X CAN USB interfaces")
