Stefan Hajnoczi 98e788b91a file-posix: populate pwrite_zeroes_alignment 
Linux block devices require write zeroes alignment whereas files do not.

It may come as a surprise that block devices opened in buffered I/O mode
require the alignment for write zeroes requests although normal
read/write requests do not.

Therefore it is necessary to populate the pwrite_zeroes_alignment field.
