[ Upstream commit 337555744e6e39dd1d87698c6084dd88a606d60a ]

The memblock_phys_alloc_try_nid() function tries to allocate memory from
the requested node and then falls back to allocation from any node in
the system. The memblock_alloc_base() fallback used by this function
panics if the allocation fails.

Replace the memblock_alloc_base() fallback with the direct call to
memblock_alloc_range_nid() and update the memblock_phys_alloc_try_nid()
callers to check the returned value and panic in case of error.

This is a part of memblock refactoring, I don't think it should be applied
to -stable.

Dropped, thanks!
