ARM: pxa: Wunused-result warning in viper board file

Calling kstrtoul requires checking the result. In case of
the viper_tpm_setup function, let's fail the __setup function
if the number was invalid.

Without this patch, building viper_defconfig results in:

arch/arm/mach-pxa/viper.c: In function 'viper_tpm_setup':
arch/arm/mach-pxa/viper.c:771:10: warning: ignoring return value of 'kstrtoul', declared with attribute warn_unused_result [-Wunused-result]
