target/user: Allow user to set block size before enabling device
The capability of setting hw_block_size was added along with 9c1cd1b68 "target/user: Only support full command pass-through", though default setting override the user specified value during the enabling of device, which called by target_configure_device() to set block_size matching hw_block_size, result in user not able to set different block size other than default 512. This patch would use existing hw_block_size value if already set, otherwise it would be set to default value(512). Update: Fix the coding style issue. (Drop unnecessary re-export of dev->dev_attrib.block_size - nab) Signed-off-by: Sheng Yang <sheng@yasker.org> Cc: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
