zonefs: Prevent uninitialized symbol 'size' warning

Browse Source 
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.
