The events group refactor (commit aa3fd66) changed the semantics of ksymbols dependency so that kernel symbols would only be loaded if a specific list was set. This broke several events which require kernel symbols in general, but not any specifically (being set through argument "parameter" lists). Fix this by bringing back previous semantics.
print_mem_dump trigger currently fails when failing to query a symbol. However print_mem_dump can potentially include many symbols in its parameters, and shouldn't fail the whole trigger based on one symbol. Skip the error return when a symbol query fails and log a WARN level message instead.

Maybe this should be DEBUG level instead?

This reverts commit 1a47a4e. This is done because the commit cause the "symbols_loaded" event to file and also cause many error messages that weren't seen before.
