Sudhakar Kuppusamy 6b5c671d35 commands/menuentry: Fix for out of bound access
A menu entry with an empty title leads to an out-of-bounds access at
"ch = src[len - 1]", i.e., "src" is empty and "len" is zero. So, fixing
this by checking the menu entry title length and throwing an error if
the length is zero.
