isofs: release zisofs block pointer buffer head
zisofs_fill_pages() reads the compressed block pointer table. The error
paths release the current buffer_head, the loop also releases the old
buffer_head when it advances. However, the success path leaves the last
buffer_head referenced. Release it before returning success.
