  memblock: report failures when memblock_can_resize is not set (2023-09-28 09:04:33 +0300)

----------------------------------------------------------------
memblock: report failures when memblock_can_resize is not set

Numerous memblock reservations at early boot may exhaust static
memblock.reserved array and it is unnoticed because most of the callers don't
check memblock_reserve() return value.

In this case the system will crash later, but the reason is hard to identify.

Replace return of an error with panic() when memblock.reserved is exhausted
before it can be resized.
