[PATCH 1/2] ls core command: remove unreachable code

[Francesco Lavra]

The path local variable in grub_core_cmd_ls() is assigned values such 
that it cannot be NULL, so a couple of if blocks can be removed as they 
are never executed.

        * grub-core/kern/corecmd.c (grub_core_cmd_ls): Remove unreachable code.
