Andreas Gruenbacher dd0ecf5441 gfs2: Fix deadlock between gfs2_{create_inode,inode_lookup} and delete_work_func 
In gfs2_create_inode and gfs2_inode_lookup, make sure to cancel any pending
delete work before taking the inode glock.  Otherwise, gfs2_cancel_delete_work
may block waiting for delete_work_func to complete, and delete_work_func may
block trying to acquire the inode glock in gfs2_inode_lookup.
