Subject: [PATCH v1] selftests/media_tests: fix a resource leak

From: zhujun2 <zhujun2@...s.chinamobile.com>

The opened file should be closed in main(), otherwise resource
leak will occur that this problem was discovered by code reading

Hi Dan Carpenter 
	
	I believe that the Linux kernel code is sacred and should strictly adhere to C code conventions

thanks,
[Zhu Jun]
