[PATCH net-next] drivers: net: xen-netfront: Fixed W=1 set but unused warnings

[Andrew Lunn]

drivers/net/xen-netfront.c:2416:16: warning: variable ‘target’ set but not used 
[-Wunused-but-set-variable]
 2416 |  unsigned long target;

Remove target and just discard the return value from simple_strtoul().

This patch does give a checkpatch warning, but the warning was there
before anyway, as this file has lots of checkpatch warnings.
