parisc/sticon: fix reverse colors

commit bec05f33eb upstream.

sticon_build_attr() checked the reverse argument and flipped
background and foreground color, but returned the non-reverse
value afterwards. Fix this and also add two local variables
for foreground and background color to make the code easier
to read.
