[PATCH] crypto/testmgr: fix uninitialized warning from gcc

[Mike Frysinger]

Since err is not set to a value if tcount is 0, gcc issues a warning:
crypto/testmgr.c: In function âtest_cprngâ:
crypto/testmgr.c:1204: warning: âerrâ may be used uninitialized in this function

Since this is test code, forcing initialized sanity should be fine.
