    gdbserver: return tracked register status in regcache_raw_read_unsigned
    
    In regcache_raw_read_unsigned, we unconditionally return REG_VALID as
    the register status.  This does not seem right, since the register may
    in fact be in another state, such as REG_UNAVAILABLE.  Return the
    tracked status.
