x86/efi: Show actual ending addresses in efi_print_memmap

Adjust efi_print_memmap to print the real end address of each
range, not 1 byte beyond. This matches other prints like those
for SRAT and nosave memory.

While investigating grub persistent memory corruption issues, it
was helpful to make this table match the ending address
convention used by:
* the kernel's e820 table prints
	BIOS-e820: [mem 0x0000001680000000-0x0000001c7fffffff] reserved
* the kernel's nosave memory prints
	PM: Registered nosave memory: [mem 0x880000000-0xc7fffffff]
* the kernel's ACPI System Resource Affinity Table prints
	SRAT: Node 1 PXM 1 [mem 0x480000000-0x87fffffff]
* grub's lsmmap and lsefimmap commands
	reserved  0000001680000000-0000001c7fffffff 00600000     24GiB UC WC WT WB NV
* the UEFI shell's memmap command
	Reserved   000000007FC00000-000000007FFFFFFF 0000000000000400 0000000000000001

For example, if you grep all the various logs for c7fffffff, you
won't find the kernel's line if it uses c80000000.

Also, change the closing ) to ] to match the opening [.
