x86/boot/e820: Remove pointless early_panic() indirection

early_panic() is a pointless wrapper around panic():

	static void __init early_panic(char *msg)
	{
		early_printk(msg);
		panic(msg);
	}

panic() will already do a printk() of 'msg', and an early_printk() if
earlyprintk is enabled. There's no need to print it separately.

Remove the function.
