pcm: fix snd_pcm_mmap_hw_avail() near the boundary

This function returned incorrect results when hw.ptr was near the
boundary and hw.appl_ptr was near zero. Here "incorrect" means "greater
than the boundary".

The result was incorrect, because it was used as a return value of
various *_rewindable() functions and also as the delay for ioplug.
