[SRU] [B] [PATCH 1/1] UBUNTU: SAUCE: zfs: fix build error with tracepoints enabled

[Andrea Righi]

BugLink: https://bugs.launchpad.net/bugs/1828763

In b49151d684f44 tx_waited has been renamed to tx_dirty_delayed, but
only in the tracepoint definition (in trace_dmu.h) and not in the rest
of the code, causing build errors if zfs tracepoints are enabled.

Fix by reverting tx_dirty_delayed back to the original name tx_waited.

NOTE: this bug doesn't show up in regular kernel builds, because zfs
tracepoints are not enabled by default.
