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.
