Refactor ntfs resize code (#790842) 

Refactor nested if-then-else into a sequence of if fail return early.
Makes the code simpler to understand and converts separate
OperationDetail::set_status() calls for success or error into a single
call using ternary conditional matching how it is or was done everywhere
else.  This is also ready for status and error capture refactoring.

Bug 790842 - Report libparted messages into operation details at the
             point at which they occur
