generic: test reporting of wb errors via syncfssyncfs
Add a test for new syncfs error reporting behavior. When an inode fails
to be written back, ensure that a subsequent call to syncfs() will also
report an error.
This behavior is currently dependent on this patchset being merged:
vfs: have syncfs() return error when there are writeback errors
