[PATCH v2 2/2] crash: update stale NR_CPUS_DEFAULT references in elfcorehdr sizing docs

[Ionut Nechita (Wind River)]

From: Ionut Nechita <ionut.nechita@xxxxxxxxxxxxx>

The elfcorehdr over-allocation for crash hotplug is now computed from
CONFIG_NR_CPUS rather than CONFIG_NR_CPUS_DEFAULT, but two pieces of
documentation still name the old symbol: the comment above
crash_handle_hotplug_event() and the CRASH_MAX_MEMORY_RANGES help text.

Update both so they describe what the code actually does and do not
mislead people sizing CRASH_MAX_MEMORY_RANGES.

Documentation only, no functional change.
