MFC r220062, r220173:
r220062:
In g_gate_create() there is a window between when g_gate_softc is
registered in g_gate_units array and when its sc_provider field is
filled. If during this period g_gate_units is accessed by another
thread that is checking for provider name collision the crash is
possible.
Fix this by adding sc_name field to struct g_gate_softc. In
g_gate_create() when g_gate_softc is created but sc_provider is still
not sc_name points to provider name stored in the local array.

r220173:
Increase debug level on g_gate device destruction and add message on
device creation.
