libarchive: Avoid bogus conversion warning from PGI compiler
We cannot suppress PGI compiler warnings completely because even with the "-w" flag the compiler still writes a message containing "compilation completed with warnings" to stderr. A warning is triggered by expressions like test ? NULL : ptr_to_const_char test ? ".." : ptr_to_const_char that the PGI compiler handles incorrectly. It chooses the pointer type of the first option (either void* or char*) and warns about conversion of the second without a cast. Flip the expression logic to !test ? ptr_to_const_char : NULL !test ? ptr_to_const_char : ".." to help the compiler choose the proper result type.
