[PATCH v2 3/6] rpc: Change return type of virNetClientAddProgram to void

[Alexander Kuznetsov <kuznetsovam@xxxxxxxxxxxx>]

This function return value is invariant since VIR_EXPAND_N check
removal in 7d2fd6e, so change its type and remove all dependent checks.

Found by Linux Verification Center (linuxtesting.org) with Svace.
