powerpc/kexec_file: Use inclusive range checks for excluded memory

Browse Source 
arch_check_excluded_range() checks if a kexec segment overlaps an
excluded memory range.

Both ranges use inclusive end addresses, but the overlap check uses
exclusive comparisons. This skips ranges with start == ->ranges[i].end
or end == ->ranges[i].start. Use inclusive comparisons instead.

Fixes: 6e5250eaa6 ("powerpc/crash: use generic APIs to locate memory hole for kdump")
