remoteproc: core: Set trace buffer name for diagnostics

Browse Source 
rproc_trace_read() (in remoteproc_debugfs.c) prints the name of a
trace buffer whose device address could not be resolved, but nothing
ever assigns trace_mem.name, so that the diagnostics always prints
an empty string:

	Trace  not available

Copy the generated "trace%d" name into the memory entry, so the
diagnostics identifies the buffer failed to translate.
