zpool_read_label doesn't need the full labels including uberblocks. It only needs the vdev_phys_t. This reduces by half the amount of data read to check for a label, speeding up "zpool import", "zpool labelclear", etc. Originally committed as https://cgit.freebsd.org/src/commit/?id=63f8025d6acab1b334373ddd33f940a69b3b54cc Obtained from: FreeBSD Sponsored by: Spectra Logic Corp, Axcient Reviewed-by: Jorgen Lundman <lundman@lundman.net> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Alek Pinchuk <apinchuk@axcient.com> Signed-off-by: Alan Somers <asomers@gmail.com> Closes #11467
