zonefs: Prevent uninitialized symbol 'size' warning
In zonefs_file_dio_append(), initialize the variable size to 0 to prevent compilation and static code analizers warning such as: New smatch warnings: fs/zonefs/file.c:441 zonefs_file_dio_append() error: uninitialized symbol 'size'. The warning is a false positive as size is never actually used uninitialized. No functional change.
