MIPS: malta: memory.c: Initialize the 'memsize' variable
If the 'memsize' environmental variable is not set by the bootloader the 'memsize' variable is not initialized, leading to potential memory problems. This patch fixes the problem by setting the initial value to '0' to force the kernel to set a good default memory size.
