flash/nor/jtagspi: 'retval' may be used uninitialized 

Problem
As my compiler has "warnings being treated as errors" on, it shows the
error message:
  error: 'retval' may be used uninitialized in this function

Investigation
Nothing wrong with the logic, 'retval' would have a value before returning.
Just wanna get rid of the compiling "warning as error" message.

Solution
Provide a reasonable default value
