tests: hostdev: Move variable declaration inside CHECK_LIST_COUNT()

The 'actualCount' variable, formerly just 'count', is only used
internally by the macro, so it's better to move its declaration
inside the macro as well: this way, it doesn't have to be declared
by every single user.

The new name is less generic to make clashes less likely.
