arch/arm/boot/compressed/decompress.c: fix build error due to lz4 changes

  include/linux/cpumask.h: In function 'cpumask_parse':
  include/linux/cpumask.h:636:21: error: implicit declaration of function 'strchrnul'; did you mean 'strchr'? [-Werror=implicit-function-declaration]

Because arch/arm/boot/compressed/decompress.c does

#define _LINUX_STRING_H_

preventing linux/string.h from providing strchrnul.  It also #includes
asm/string.h, which for arm has a declaration of strchr(), explaining why
this didn't use to fail.
