qede: fix build with gcc 6

With gcc >= 6.0, qede base driver fails to build with:
drivers/net/qede/base/ecore_cxt.c: In function 'ecore_cdu_init_common':
cc1: error: left shift of negative value [-Werror=shift-negative-value]

Since the base drivers are untouchable, work around by disabling
the warning.

Fixes: ec94dbc57362 ("qede: add base driver")
