[PATCH] lib/asn1_encoder: Remove redundant assignment to ret

[Yang Li]

Variable 'ret' is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed.

Clean up the following clang-analyzer warning:

lib/asn1_encoder.c:167:2: warning: Value stored to 'ret' is never read
[clang-analyzer-deadcode.DeadStores]
