seq: Fix for snd_seq_parse_address()

snd_seq_parse_address() uses strncmp() to compare the client name
in the string argument with the existing clients, until it finds one
name matching the same leading characters. This may produce wrong
results when there are two sequencer clients with similar names.

Example: "KMidimon" : "Kmid"
