unifdef: fix invalid array access when nesting limit exceeded
If the number of nested #if blocks exceeds 64, nest() increments
the nesting depth and then reports an error. The message includes
the line number for the start of the current #if block, which is
read from past the end of the relevant array.
Avoid the out-of-bounds read by reporting the error and exiting
before the nesting depth has a chance to increase.
