Fixed bug 5339 - Minor memory leak in SDL_x11events.c

wcodelyokoyt

The atom name that X11_GetAtomName() returns never gets freed, which result in a minor memory leak (14 bytes?) every time the user drops a file on a window.
You can see the line in question here:
6b6170caf6/src/video/x11/SDL_x11events.c (L1350)

Fix: call XFree on name after the while loop.
