Subject: [PATCH] winmm: Buffer size must be at least MMIO_DEFAULTBUFFER (8192)
 bytes.

mmioOpen() with the length of buffer set to 0 expects the buffer to be at least
MMIO_DEFAULTBUFFER (8192) bytes in size, and using buffer of smaller size can
lead to various problems when the buffer actually gets used.
