mips: Fix the increased mem parameter size
The added "mem=size@start" parameter actually corresponds to
"crashkernel=YM@XM", but 1 byte is missing when calculating
the size, so 1 byte should be added.
For example, when using crashkernel=108M@64M (110592K@65536K):
Without this patch:
the mem parameter added is: mem=110591K@65536K
With this patch:
the mem parameter added is: mem=110592K@65536K
Fixes: 0eac64052636 ("kexec: mips: Fix mem parameters")
