[PATCH v1 1/2] hostmem: use a static size for maxnode, validate policy everywhere

Previously we would calculate the last set bit in the mask, and add 2 to that value to get the maxnode value. This is unnecessary since the mbind syscall allows the bitmap to be any (reasonable) size as long as all the unused bits are clear. This also adds policy validation in multiple places so

This is needed for cases where we want to make sure that a shared memory region gets allocated from a specific NUMA node. This is impossible to do with mbind(2) because it ignores the policy for memory mapped with MAP_SHARED. We work around this by calling set_mempolicy from prealloc threads
