Subject: [PATCH 3.18 108/150] mtd: tests: abort torturetest on erase errors

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brian Norris <computersforpeace@...il.com>

commit 68f29815034e9dc9ed53cad85946c32b07adc8cc upstream.

The torture test should quit once it actually induces an error in the
flash. This step was accidentally removed during refactoring.

Without this fix, the torturetest just continues infinitely, or until
the maximum cycle count is reached. e.g.:

   ...
   [ 7619.218171] mtd_test: error -5 while erasing EB 100
   [ 7619.297981] mtd_test: error -5 while erasing EB 100
   [ 7619.377953] mtd_test: error -5 while erasing EB 100
   [ 7619.457998] mtd_test: error -5 while erasing EB 100
   [ 7619.537990] mtd_test: error -5 while erasing EB 100
   ...
