powerpc/fadump: Account for memory_limit while reserving memory
If the memory chunk found for reserving memory overshoots the memory limit imposed, do not proceed with reserving memory. Default behavior was this until commit140777a3d8
("powerpc/fadump: consider reserved ranges while reserving memory") changed it unwittingly. Fixes:140777a3d8
