wined3d: Avoid unsynchronized buffer update when reloading whole buffer.

Fixes bc019fcbbd7f0014280a292bc58ef618cfbe34c7. Previously, we had the
NOSYNC flag instead of the SYNC flag. When the NOSYNC flag was set the
buffer was mapped with GL_MAP_UNSYNCHRONIZED_BIT. Now, when the SYNC
flag is not set the buffer is mapped with GL_MAP_UNSYNCHRONIZED_BIT.
