xen/arm: efi: Avoid out-of-bounds write in meminfo_add_bank

Commit 2c77db77 "xen/arm: efi: Avoid duplicating the addition of a new
bank", introduced a new function meminfo_add_bank that add a new bank.
This new code fails to check correctly the size of the array which may
result to an out-of-bounds write.
