block: move bd_set_size() above rescan_partitions() in __blkdev_get()
commit 7e69723fef8771a9d57bd27d36281d756130b4b5 upstream.
02e352287a4 (block: rescan partitions on invalidated devices on
-ENOMEDIA too) relocated partition rescan above explicit bd_set_size()
to simplify condition check. As rescan_partitions() does its own bdev
size setting, this doesn't break anything; however,
rescan_partitions() prints out the following messages when adjusting
bdev size, which can be confusing.
sda: detected capacity change from 0 to 146815737856
sdb: detected capacity change from 0 to 146815737856
This patch restores the original order and remove the warning
messages.
stable: Please apply together with 02e352287a4 (block: rescan
partitions on invalidated devices on -ENOMEDIA too).
