Fix i386 vectorizer cost of FP scalar MAX_EXPR and MIN_EXPR

I introduced a bug by last minute cleanups unifying the scalar and vector SSE conditional.
This patch fixes it and restores cost of 1 of SSE scalar MIN/MAX

Bootstrapped/regtested x86_64-linux, comitted.

gcc/ChangeLog:

	PR target/105275
	* config/i386/i386.cc (ix86_vector_costs::add_stmt_cost): Fix cost of FP scalar
	MAX_EXPR and MIN_EXPR
