usb: gadget: u_audio: fix pcm/card naming in g_audio_setup()
Fix below smatch (v0.5.0-4443-g69e9094e11c1) warnings:
drivers/usb/gadget/function/u_audio.c:607 g_audio_setup() warn: strcpy() 'pcm_name' of unknown size might be too large for 'pcm->name'
drivers/usb/gadget/function/u_audio.c:614 g_audio_setup() warn: strcpy() 'card_name' of unknown size might be too large for 'card->driver'
drivers/usb/gadget/function/u_audio.c:615 g_audio_setup() warn: strcpy() 'card_name' of unknown size might be too large for 'card->shortname'
Below commits performed a similar 's/strcpy/strlcpy/' rework:
* v2.6.31 commit 8372d4980fbc ("ALSA: ctxfi - Fix PCM device naming")
* v4.14 commit 003d3e70dbeb ("ALSA: ad1848: fix format string overflow warning")
* v4.14 commit 6d8b04de87e1 ("ALSA: cs423x: fix format string overflow warning")
