[v2,0/2] sd_zbc fixes

Message

A couple of patches to fix 2 issues with the zbc code:
* A potential NULL pointer dereference in sd_is_zoned(), if that
  function is called when sdkp->device is not yet set (e.g. if an error
  happen early in sd_probe()).
* Make sure that sdkp zone information memory is never leaked.

Changes from v1:
* Added reviewed-by and tested-by tags in patch 1
* Changed patch 2 to rename sd_zbc_clear_zone_info() to
  sd_zbc_free_zone_info() and remove sd_zbc_release_disk().
