fs: guard_bio_eod() needs to consider partitions
commit 67f2519fe2903c4041c0e94394d14d372fe51399 upstream.
guard_bio_eod() needs to look at the partition capacity, not just the
capacity of the whole device, when determining if truncation is
necessary.
[ 60.268688] attempt to access beyond end of device
[ 60.268690] unknown-block(9,1): rw=0, want=67103509, limit=67103506
[ 60.268693] buffer_io_error: 2 callbacks suppressed
[ 60.268696] Buffer I/O error on dev md1p7, logical block 4524305, async page read
Fixes: 74d46992e0d9 ("block: replace bi_bdev with a gendisk pointer and partitions index")
