netdevsim: Fix build error without CONFIG_INET

Browse Source 
If CONFIG_INET is not set, building fails:

drivers/net/netdevsim/dev.o: In function `nsim_dev_trap_report_work':
dev.c:(.text+0x67b): undefined reference to `ip_send_check'

Use ip_fast_csum instead of ip_send_check to avoid
dependencies on CONFIG_INET.
