imap: Fix o_stream_is_corked() assert check

All the callers cork the stream, so this can only mean that the corking
failed because the connection was already closed. Continue handling the
input anyway.

Fixes:
Panic: file imap-client.c: line 1236 (client_handle_input): assertion failed: (o_stream_is_corked(client->output))
