[PATCH 17/20] misc: genwqe: card_base: Do not pass unused argument 'fatal_err'

[Lee Jones]

'fatal_err' is taken as an argument to a static function which is only
invoked once.  During this invocation 'fatal_err' is not set.  There
doesn't appear to be a good reason to keep it around.

Also fixes the following W=1 kernel build warning:

 drivers/misc/genwqe/card_base.c:588: warning: Function parameter or member 'fatal_err' not described in 'genwqe_recover_card'
