cifs: add support for fallocate mode 0 for non-sparse files
RHBZ 1336264 When we extend a file we must also force the size to be updated. This fixes an issue with holetest in xfs-tests which performs the following sequence : 1, create a new file 2, use fallocate mode==0 to populate the file 3, mmap the file 4, touch each page by reading the mmapped region.
