Fixes rust-lang#4678: the previous wording 'statements don't evaluate to a value' followed by 'Therefore, nothing is returned' internally contradicts the immediately preceding clause that names '()', the unit type, as the type produced. Rewrite the sentence to a single thread that says statements evaluate to () which doesn't satisfy the declared i32 return type.

Fixes #4678
Summary
Chapter 3.3 says 'statements don't evaluate to a value, which is
expressed by (), the unit type. Therefore, nothing is returned'.
That wording implicitly names () then says 'nothing is returned',
contradicting the immediately preceding clause. Reword to one
unbroken sentence: statements evaluate to () which doesn't satisfy
the declared i32 return type.
The compiler error and the suggestion (remove the semicolon) remain
correct and unchanged.
