dump: eliminate DumpState.page_shift ("guest's page shift")
Just use TARGET_PAGE_BITS.
"DumpState.page_shift" used to have type "uint32_t", while the replacement
TARGET_PAGE_BITS has type "int". Since "DumpState.page_shift" was only
used as bit shift counts in the paddr_to_pfn() and pfn_to_paddr() macros,
this is safe.
