From btree_read_extent_buffer_pages(), currently repair_io_failure() can be called with mirror_num being zero when submit_one_bio() returned an error before. This used to cause a BUG_ON(!mirror_num) in repair_io_failure() and indeed this is not a case that needs the I/O repair code to rewrite disk blocks. This commit prevents calling repair_io_failure() in this case and thus avoids the BUG_ON() and malfunction. Signed-off-by:
