crash_core: fix and simplify the logic of crash_exclude_mem_range()
The purpose of crash_exclude_mem_range() is to remove all memory ranges
that overlap with [mstart-mend]. However, the current logic only removes
the first overlapping memory range.
Commit a2e9a95d2190 ("kexec: Improve & fix crash_exclude_mem_range() to
handle overlapping ranges") attempted to address this issue, but it did
not fix all error cases.
Let's fix and simplify the logic of crash_exclude_mem_range().
