Remove redundant call of argsList->current() from loops in CSSParser
Remove redundant call of argsList->current() from loops in CSSParser

while loops in CSSParser call argList->current() function at the start
of each iteration, but this is redundant because argsList->next() at
the end of the iteration calls the argList->current() and returns the
result.
