xfs: consider shutdown in bmapbt cursor delete assert
The assert in xfs_btree_del_cursor() checks that the bmapbt block allocation field has been handled correctly before the cursor is freed. This field is used for accurate calculation of indirect block reservation requirements (for delayed allocations), for example. generic/019 reproduces a scenario where this assert fails because the filesystem has shutdown while in the middle of a bmbt record insertion. This occurs after a bmbt block has been allocated via the cursor but before the higher level bmap function (i.e. xfs_bmap_add_extent_hole_real()) completes and resets the field. Update the assert to accommodate the transient state if the filesystem has shutdown. While here, clean up the indentation and comments in the function.
