block: revert "block: fix bd_size_lock use"
With the removal of the skd driver, using IRQ safe locking of a bdev bd_size_lock spinlock to protect the bdev inode size is not necessary anymore as there is no other known driver using this lock under an IRQ disabled context (e.g. calling set_capacity() with IRQ disabled). Revert commit 0fe37724f8e7 ("block: fix bd_size_lock use") which introduced the IRQ safe change. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
