arm64: Fix shift warning in arch/arm64/mm/dump.c

When building with 48-bit VAs and 16K page configuration, it's possible
to get the following warning when building the arm64 page table dumping
code:

arch/arm64/mm/dump.c: In function ‘walk_pud’:
arch/arm64/mm/dump.c:274:102: warning: right shift count >= width of type [-Wshift-count-overflow]

This is because pud_offset(pgd, 0) performs a shift to the right by 36
while the value 0 has the type 'int' by default, therefore 32-bit.

This patch modifies all the p*_offset() uses in arch/arm64/mm/dump.c to
use 0UL for the address argument.
