fbdev: viafb: fix typo in hw_bitblt_1 and hw_bitblt_2
There are some actions with value 'tmp' but 'dst_addr' is checked instead.
It is obvious that a copy-paste error was made here and the value
of variable 'tmp' should be checked here.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
