Tanya Agarwal e7b7f5a170 lib: 842: Improve error handling in sw842_compress() ...

[ Upstream commit af324dc0e2 ]

The static code analysis tool "Coverity Scan" pointed the following
implementation details out for further development considerations:
CID 1309755: Unused value
In sw842_compress: A value assigned to a variable is never used. (CWE-563)
returned_value: Assigning value from add_repeat_template(p, repeat_count)
to ret here, but that stored value is overwritten before it can be used.

Conclusion:
Add error handling for the return value from an add_repeat_template()
call.
