[PATCH] osmo-msc[master]: a_reset: Add additional "a_reset_alloc" argument

[Harald Welte]

Review at  https://gerrit.osmocom.org/6325

a_reset: Add additional "a_reset_alloc" argument

Using this argument we can create the state machine in the
"already connected" state, i.e. without starting an outbound
RESET procedure.
