The variable 'first' is assigned 0 inside the while loop in the if block
but it is not used in the if block and is only used in the else block.
So, remove the unneeded assignment and move the variable in the else block.

The resultant binary stayed same after this change. Verified with
md5sum which remained same with and without this change.
