When calling get_fslist on a kernel doesn't support
BTRFS_IOC_GET_FSLIST, an error message will output but the codes will
continue using the old way to scan mounted fs.

Since the error message will fail xfstest/btrfs/006 testcase and there
is a fallback way, the message should not be printed.

Also other error message in get_fslist is not needed since the functions
in utils.c should not print any thing and caller will handle the error.
This patch just remove the unneeded perror messages.
