[PATCH 5.8 208/232] fs/minix: remove expected error message in block_to_path()

[Greg Kroah-Hartman]

From: Eric Biggers <ebiggers@xxxxxxxxxx>

[ Upstream commit f666f9fb9a36f1c833b9d18923572f0e4d304754 ]

When truncating a file to a size within the last allowed logical block,
block_to_path() is called with the *next* block.  This exceeds the limit,
causing the "block %ld too big" error message to be printed.

This case isn't actually an error; there are just no more blocks past that
point.  So, remove this error message.
