libzfs: handle EDOM error in zpool_create

When creating a pool with devices that have incompatible block sizes,
the kernel returns EDOM. However, zpool_create() did not handle this
errno, falling through to zpool_standard_error() which produced a
confusing message about invalid property values.

Add a case EDOM handler in zpool_create() to return EZFS_BADDEV with
a descriptive auxiliary message, consistent with the existing EDOM
handler in zpool_vdev_add().
