block: move bd_set_size() above rescan_partitions() in __blkdev_get()
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).
