Currently rdmsr and wrmsr commands have own MSR support detection code. This code is the same. So, it is duplicated. Additionally, this code cannot be reused by others. Hence, extract this code to a function and make it public. By the way, improve a code a bit. Additionally, use GRUB_ERR_BAD_DEVICE instead of GRUB_ERR_BUG to signal an error because errors encountered by this new routine are not bugs.
