[PATCH]Fix wrong use of memparse in efi.c

[Zou Nan hai <nanhai.zou@intel.com>]

The check of (end != cp) after memparse in efi.c looks wrong to me.
The result is that we can't use mem= and max_addr= kernel parameter at
the same time.

The following patch removed the check just like other arches do.
