[patch 3/2] drivers/char/vt.c: remove unnecessary code

[colbuse@ensisun.imag.fr]

We could change an affectation into an incrementation by this patch, and,
so far I know, incrementing is quicker than or as quick as setting
a variable (depends on the architecture).

Please _don't_ apply this, but tell me what you think about it.
Note that npar is unsigned.
