    Fix use of wrong struct i387_xsave field in i387_cache_to_xsave
    
    gdb/gdbserver/ChangeLog:
    
            * i387-fp.c (i387_cache_to_xsave): In look over
            num_avx512_zmmh_high_registers, replace use of struct i387_xsave
            zmmh_low_space field by use of zmmh_high_space.
    
    Tested on x86_64-linux, using boards/native-gdbserver.exp.
