Title: Switch KM_SLEEP to KM_PUSHPAGE

Two more locations where KM_SLEEP was used in a call which must use
KM_PUSHPAGE were found while using the zpool upgrade command.
See commit b8d06fc for additional details.

Also make a small correction to the comment block above
dsl_dir_open_spa().

Closes #1268
