block: skip bio_check_eod for partition-remapped bios
When an already remapped bio is resubmitted (e.g. by blk_queue_split),
bio_check_eod will compare the remapped bi_sector against the size
of the partition, leading to spurious I/O failures.
Skip the EOD check in this case.
Fixes: 309dca309fc3 ("block: store a block_device pointer in struct bio")
