BaseTools/DevicePath: fix GCC build error in print_mem(), and clean it up
Currently "BaseTools/Source/C/DevicePath/DevicePath.c" fails to build with
GCC48:
> DevicePath.c: In function 'print_mem':
> DevicePath.c:109:5: error: 'for' loop initial declarations are only
> allowed in C99 mode
> for (size_t i=0; i<n; i++) {
> ^
> DevicePath.c:109:5: note: use option -std=c99 or -std=gnu99 to compile
> your code
In addition, the print_mem() function does not conform to the edk2 coding
style:
- we use CamelCase and no underscores in identifiers,
- the types and type qualifiers should follow the edk2 style,
- initialization as part of definition is forbidden for local variables.
Clean these up.
While updating the print_mem()/PrintMem() call sites, also remove the
superfluous parentheses around the second argument.
