Fix to make clang happy

Browse source 
POSIX states that 'd_name' in 'struct dirent' is char[], so it cannot be NULL.
This will result in the compiler complainting about an expression which always
evaluates to true ... for this compiler (clang). But in some implementations
'd_name' is a 'char*' that's why it's better to keep the check for possible
NULL.
