[PATCH 2/2] s390: Fix possibly wrong size in strncmp (smsglucv)

[Stefan Weil <weil@mail.berlios.de>]

This error was reported by cppcheck:
drivers/s390/net/smsgiucv.c:63: error: Using sizeof for array given as function argument returns the size of pointer.

Although there is no runtime problem as long as sizeof(u8 *) == 8,
this misleading code should get fixed.
