Tom Lendacky 62d5e970d0 x86/sev: Change npages to unsigned long in snp_accept_memory() ...

In snp_accept_memory(), the npages variables value is calculated from
phys_addr_t variables but is an unsigned int. A very large range passed
into snp_accept_memory() could lead to truncating npages to zero. This
doesn't happen at the moment but let's be prepared.
