[PATCH 13/14] mkfs: catch unknown format in protofile parsing

[Eric Sandeen]

As the code stands today we can't get an unknown format in the
last case statement, but Coverity warns that if we ever do, we'll
use an uninitialized "ip" in the call to libxfs_trans_log_inode().

Adding a default: case to catch unknown formats is defensive and
makes the checker happy.
