Illumos 4914 - zfs on-disk bookmark structure should be named *_phys_t

4914 zfs on-disk bookmark structure should be named *_phys_t

Porting notes:

There were a number of zfsonlinux-specific uses of zbookmark_t which
needed to be updated.  This should reduce the likelihood of further
problems like issue #2094 from occurring.

Closes #2558
