ximcp: Prevent memory leak & double free if multiple %L in string
In the highly unlikely event that TransFileName was passed a path
containing multiple %L entries, for each entry it would call
_XlcFileName, leaking the previous results, and then for each entry it
would copy from that pointer and free it, resulting in invalid pointers
& possible double frees for each use after the first one freed it.
Error: Use after free (CWE 416)
Use after free of pointer 'lcCompose'
at line 358 of nx-X11/lib/X11/imLcPrs.c in function 'TransFileName'.
Previously freed at line 360 with free.
Error: Use after free (CWE 416)
Use after free of pointer 'lcCompose'
at line 359 of nx-X11/lib/X11/imLcPrs.c in function 'TransFileName'.
Previously freed at line 360 with free.
Error: Double free (CWE 415)
Double free of pointer 'lcCompose'
at line 360 of nx-X11/lib/X11/imLcPrs.c in function 'TransFileName'.
Previously freed at line 360 with free.
