zvol queue limits initialization depends on `zv_volblocksize`, but it is initialized later, leading to several limits being initialized with incorrect values, including `max_discard_*` limits. This also causes `blkdiscard` command to consistently fail, as `blk_ioctl_discard` reads `bdev_max_discard_sectors()` limits as 0, leading to failure. The fix is straightforward: initialize `zv->zv_volblocksize` early, before setting the queue limits. This PR should fix `zvol/zvol_misc/zvol_misc_trim` failure on recent PRs, as the test case issues `blkdiscard` for a zvol. Additionally, `zvol_misc_trim` was recently enabled in `6c7d41a`, which is why the issue wasn't identified earlier.
