ocfs2: cancel dqi_sync_work before freeing oinfo

In the Linux kernel, the following vulnerability has been resolved:

ocfs2: cancel dqi_sync_work before freeing oinfo

ocfs2_global_read_info() will initialize and schedule dqi_sync_work at the
end, if error occurs after successfully reading global quota, it will
trigger the following warning with CONFIG_DEBUG_OBJECTS_* enabled:

ODEBUG: free active (active state 0) object: 00000000d8b0ce28 object type: timer_list hint: qsync_work_fn+0x0/0x16c

This reports that there is an active delayed work when freeing oinfo in
error handling, so cancel dqi_sync_work first.  BTW, return status instead
of -1 when .read_file_info fails.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
