selftests/resctrl: Check for return value after write_schemata()
[ Upstream commit 0d45c83b95da414e98ad333e723141a94f6e2c64 ]
MBA test case writes schemata but it does not check if the write is
successful or not.
Add the error check and return error properly.
Fixes: 01fee6b4d1f9 ("selftests/resctrl: Add MBA test")
