zonefs: Fix error message in zonefs_file_dio_append()

[ Upstream commit 88b170088ad2c3e27086fe35769aa49f8a512564 ]

Since the expected write location in a sequential file is always at the
end of the file (append write), when an invalid write append location is
detected in zonefs_file_dio_append(), print the invalid written location
instead of the expected write location.

Fixes: a608da3bd730 ("zonefs: Detect append writes at invalid locations")
