mrelease_test doubles the child allocation when process_mrelease() returns
ESRCH.
When size is already MAX_SIZE_MB, the current <= check still allows
another retry, causing the allocation to grow from 1024 MB to 2048 MB.
Use < instead of <= so the largest allocation attempted remains
MAX_SIZE_MB.
LLM used in discovering bug. Changes were made and reviewed manually.
