cat-file: Fix an gcc -Wuninitialized warning

Ramsay Jones · gitster · commit 803a777942b0 · 2013-03-29T23:47:00.000-07:00
After commit cbfd5e1 ("drop some obsolete "x = x" compiler warning hacks", 21-03-2013) removed a gcc specific hack, older versions of gcc now issue an "'contents' might be used uninitialized" warning. In order to suppress the warning, we simply initialize the variable to NULL in it's declaration.
