eth: fbnic: fix s390 build.
Building the fbnic nn s390, yield a build bug:
In function ‘fbnic_config_drop_mode_rcq’,
inlined from ‘fbnic_enable’ at drivers/net/ethernet/meta/fbnic/fbnic_txrx.c:1836:4:
././include/linux/compiler_types.h:510:45: error: call to ‘__compiletime_assert_919’ declared with attribute error: FIELD_PREP: value too large for the field
The relevant mask is 9 bits wide, and the related value is the cacheline
aligned size of struct skb_shared_info.
On s390 the cacheline size is 256 bytes, and skb_shared_info minimum
size on 64 bits system is 320 bytes.
Avoid building the driver for such arch.
