Andrey Konovalov 579fb0ac08 kasan: add wrappers for vmalloc hooks 
Add wrappers around functions that [un]poison memory for vmalloc
allocations.  These functions will be used by HW_TAGS KASAN and therefore
need to be disabled when kasan=off command line argument is provided.

This patch does no functional changes for software KASAN modes.
