null_blk: use non-deprecated lib functions
Use library helper memcpy_page() to copy source page into destination
instead of having duplicate code in copy_to_nullb() & copy_from_nullb().
In copy_from_nullb() also replace the memset call with zero_user().
Use library helper memset_page() to set the buffer to 0xFF instead of
having duplicate code.
This also removes deprecated API kmap_atomic() from copy_to_nullb()
copy_from_nullb() and nullb_fill_pattern(),
from :include/linux/highmem.h:
"kmap_atomic - Atomically map a page for temporary usage - Deprecated!"
