xfs: fix xfs_log_ticket leak in xfs_end_io() after fs shutdown
If the filesystem has shut down, xfs_end_io() currently sets an
error on the ioend and proceeds to ioend destruction. The ioend
might contain a truncate transaction if the I/O extended the size of
the file. This transaction is only cleaned up in
xfs_setfilesize_ioend(), however, which is skipped in this case.
This results in an xfs_log_ticket leak message when the associate
cache slab is destroyed (e.g., on rmmod).
This was originally reproduced by xfs/141 on a distro kernel. The
problem is reproducible on an upstream kernel, but not easily
detected in current upstream if the xfs_log_ticket cache happens to
be merged with another cache. This can be reproduced more
deterministically with the 'slab_nomerge' kernel boot option.
Update xfs_end_io() to proceed with normal end I/O processing after
an error is set on an ioend due to fs shutdown. The I/O type-based
processing is already designed to handle an I/O error and ensure
that the ioend is cleaned up correctly.
