reset: remove name variable from reset context

The reset context contains a string buffer to allow for setting
a human readable name, that is then displayed in the logs. Since
OSMO-FSMs already have such a feature there is no need for an
extra name variable.

Use LOGPFSML and the name parameter of osmo_fsm_inst_alloc()
to display the name of the FSM

Fixes: Coverity CID#178664
