[PATCH 4/4] fuse2fs: print the function name in error messages, not the file name

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

It would be nice to know which fuse op actually causes failures such as:
FUSE2FS (sda4): Directory block checksum does not match directory block at ../../misc/fuse2fs.c:819.

The filename is utterly pointless, there's only one for the whole
daemon.
