Fix stack assignment during CPU initialization

There are two errors in the code. The first one is a missing
$ sign in mov _stack, %esp. Thanks to Ronald G Minnich for
catching that bug.

The second bug is the 'incl %eax', which shouldn't be there, as
there's no secondary CPU with index 0. CPU0 uses always the stack
below _estack.
