Subject: [PATCH] xtensa: tlb: include <asm/tlb.h> for missing prototype

Add the prototype for check_tlb_sanity() to <asm/tlb.h> and use that
header to prevent a build warning:

arch/xtensa/mm/tlb.c:273:6: warning: no previous prototype for 'check_tlb_sanity' [-Wmissing-prototypes]
  273 | void check_tlb_sanity(void)
