misc-utils: flashcp: Fix uninitialized variable ‘wrlast_buf’ compiling warning

The compiler compains following message:
 misc-utils/flashcp.c:439:3: warning: ‘wrlast_buf’ may be used
 uninitialized in this function
It won't bring any problems because variable '‘wrlast_buf’ is always
initialized before being used. Fix the warning by setting 'wrlast_buf'
as NULL when declaring it.
