ZIL: Reduce scope of per-dataset zl_issuer_lock. 
Before this change ZIL copied all log data while holding the lock.
It caused huge lock contention on workloads with many big parallel
writes.  This change splits the process into two parts: first,
zil_lwb_assign() estimates the log space needed for all transactions,
and zil_lwb_write_close() allocates blocks and zios while holding the
lock, then, after the lock in dropped, zil_lwb_commit() copies the
data, and zil_lwb_write_issue() issues the I/Os.

Also while there slightly reduce scope of zl_lock.
