Subject: [PATCH] Profiler: fix wrong field name

As reported in #22505, I misread the initial implemenation and named
this field wrongly. Given there has been no report about this before
this issue, it's safe to assume that the field is not widely used by
other folks and therefore, is safe to change.

Closes #22505.
