internal/coverage/decodemeta: fix coding error in func literal handling
Fix a coding error in coverage meta-data decoding in the method
decodemeta.CoverageMetaDataDecoder.ReadFunc. The code was not
unconditionally assigning the "function literal" field of the
coverage.FuncDesc object passed in, resulting in bad values depending
on what the state of the field happened to be in the object.
Fixes #57942.
