commit df561f6688fe ("treewide: Use fallthrough pseudo-keyword") from
Gustavo A. R. Silva replaced and standardized /* fallthrough */ comments
with 'fallthrough' pseudo-keyword.
However, in one of the switch-case statements, Coverity Static Analyzer
throws a warning that 'fallthrough' is unreachable due to the adjacent
'return false' statement.
Since 'fallthrough' is actually an empty "do {} while(0)" this might be
due to compiler optimizations. But that needs further investigation.
In order to fix the unreachable code warning, make adjacent 'return
false' a part of the previous if statement's else clause.
