Fix volume WR_INDIRECT log replay

Browse Source 
The portion of the zvol_replay_write() handler responsible for
replaying indirect log records for some reason never existed.
As a result indirect log records were not being correctly replayed.

This went largely unnoticed since the majority of zvol log records
were of the type WR_COPIED or WR_NEED_COPY prior to OpenZFS 7578.

This patch updates zvol_replay_write() to correctly handle these
log records and adds a new test case which verifies volume replay
to prevent any regression.  The existing test case which verified
replay on filesystem was renamed slog_replay_fs.ksh for clarity.
