parisc/sticon: fix reverse colors

Browse Source 
commit bec05f33ebc1006899c6d3e59a00c58881fe7626 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.
