x86-32, numa: Make pgdat allocation use alloc_remap()

pgdat allocation is handled differnetly from other remap allocations -
it's reserved during initialization.  There's no reason to handle this
any differnetly.  Remap allocator is initialized for every node and if
init failed the allocation will fail and pgdat allocation can fall
back to generic code like anyone else.

Remove special init-time pgdat reservation and make allocate_pgdat()
use alloc_remap() like everyone else.
