x86/boot: Use proper array element type in memset() size calculation
I changed open coded zeroing loops to explicit memset()s in the
following commit:
5e9ebbd87a99 ("x86/boot: Micro-optimize reset_early_page_tables()")
The base for the size argument of memset was sizeof(pud_p/pmd_p), which
are pointers - but the initialized array has pud_t/pmd_t elements.
Luckily the two types had the same size, so this did not result in any
runtime misbehavior.
