null_blk: clean up setting zones read-only or offline

null_set_zone_cond() takes a zone condition, even though read-only and
offline are the only zone conditions that it can set. Because of this,
it needs a WARN_ON_ONCE() to reject any other zone condition, and its
name suggests a generic helper that can set any zone condition.

Rename null_set_zone_cond() to null_set_zone_readonly_or_offline(), and
replace its zone condition argument with a bool, set_offline, which
selects between the read-only and offline conditions. Also remove the
comment above the function, as it only repeats the new function name.

zone_cond_store() keeps taking a zone condition, as it, unlike
null_set_zone_readonly_or_offline(), contains generic code, and might
be extended to support additional zone conditions in the future.

No functional change, as zone_cond_store() is only called with the
read-only or offline condition.
