[PATCH] fbdev: savage: remove unused variable

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

vga_in8() was storing the return value in tmp, but that return value
was never used again. so it should be safe to remove those variables.

just one doubt:
vga_in8() is calling savage_in8() which is a readb().
so in effect we are reading one byte from
(par->mmio.vbase + 0x8000 + 0x3da) and then discarding that value.
so if we are discarding that value then why we are reading it?
