lib: allow memparse() to accept a NULL and ignorable second parm
Extend memparse() to allow the caller to use a NULL second parameter, which
would represent no interest in returning the address of the end of the parsed
string.
In numerous cases, callers invoke memparse() to parse a possibly-suffixed
string (such as "64K" or "2G" or whatever) and define a character pointer to
accept the end pointer being returned by memparse() even though they have no
interest in it and promptly throw it away.
This (backward-compatible) enhancement allows callers to use NULL in the cases
where they just don't care about getting back that end pointer.
