powerpc/fadump: Account for memory_limit while reserving memory

commit 9a2921e5baca1d25eb8d21f21d1e90581a6d0f68 upstream.

If the memory chunk found for reserving memory overshoots the memory
limit imposed, do not proceed with reserving memory. Default behavior
was this until commit 140777a3d8df ("powerpc/fadump: consider reserved
ranges while reserving memory") changed it unwittingly.

Fixes: 140777a3d8df ("powerpc/fadump: consider reserved ranges while reserving memory")
