libsemanage: genhomedircon: fix possible double-free

When write_contexts() frees variables context and new_context_str after
a line has been successfully emitted, these variables are not reset to
NULL. This leads the function to free them again if an error occurs when
processing the next line. Fix this by always resetting these variables
at the beginning of the loop.

This issue has been found using clang's static analyzer.
