It's unnecessary to keep the variable @section_count in the function
because the device for the specific memory block will be added if
any of its memory section is present. The variable @section_count
records the number of present memory sections in the specific memory
block, which isn't needed.
Simplify the function by dropping the variable @section_count. No
functional change intended.
