Fixed bug 3297 - Horizontal and Vertical flip swapped on PSP

Littlefighter19 When trying to mirror something on the PSP, I've stumbled upon the problem, that using SDL_RenderCopyEx with SDL_FLIP_HORIZONTAL flips the image vertically, vise-versa SDL_FLIP_VERTICAL flips the image horizontally. Proposed patch would be swapping the check in line 944 with the one in line 948 in SDL_render_psp.c
