Alexander Motin 502d18a8f1 MFV r329766: 8962 zdb should work on non-idle pools
illumos/illumos-gate@e144c4e6c9

Currently `zdb` consistently fails to examine non-idle pools as it fails
during the `spa_load()` process. The main problem seems to be that
`spa_load_verify()` fails as can be seen below:

$ sudo zdb -d -G dcenter
    zdb: can't open 'dcenter': I/O error

ZFS_DBGMSG(zdb):
    spa_open_common: opening dcenter
    spa_load(dcenter): LOADING
    disk vdev '/dev/dsk/c4t11d0s0': best uberblock found for spa dcenter. txg 40824950
    spa_load(dcenter): using uberblock with txg=40824950
    spa_load(dcenter): UNLOADING
    spa_load(dcenter): RELOADING
    spa_load(dcenter): LOADING
    disk vdev '/dev/dsk/c3t10d0s0': best uberblock found for spa dcenter. txg 40824952
    spa_load(dcenter): using uberblock with txg=40824952
    spa_load(dcenter): FAILED: spa_load_verify failed [error=5]
    spa_load(dcenter): UNLOADING

This change makes `spa_load_verify()` a dryrun when ran from `zdb`. This is
done by creating a global flag in zfs and then setting it in `zdb`.
