wina11y: Drop extra location bookkeeping

The location is already retrieved on demand from the
underlying `XAccessible` in `CMAccessible::accLocation`
and the separately remembered location was just used
as fallback in case `m_xAccessible` was not (no more)
set.
However, when there is no valid associated `XAccessible`,
there is probably no value in returning any location
anyway, so just return `S_FALSE` for that case, as
other `CMAccessible` methods also do.

Whether the separately remembered `m_sLocation`
was up to date is also questionable, s.a.

This is also in line with what's mentioned in

    tdf#146306 wina11y: Retrieve accessible desc on demand

> Querying up-to-date values from the underlying
> UNO interfaces on demand instead of doing extra
> manual bookkeeping in the winaccessibility code
> may be possible for more a11y attributes in addition
> to the accessible description handled in this commit,
> but each one will have to be looked at separately.
