Henrik RydgårdandClaude Opus 5 fd72f308af sceAudio: fix a crash when reserving a channel with none free 
GetFreeChannel counted down with an unsigned loop variable, so i >= 0
was always true. With every channel already reserved it wrapped past
zero and kept indexing g_audioChans until it walked off the end -
sceAudioChReserve(-1, ...) segfaulted the emulator instead of returning
"no channels available". Reproduces on audio/sceaudio/reserve, which
crashed before printing anything.

Also gives sceVaudioChReserve the parameter checks it never had. It
took any sample count, channel count and frequency; the hardware allows
256, 1024 or 2048 samples, stereo only, and the same sample rates the
SRC channel accepts. Every value in the test now matches - what's left
there is only reschedule markers.
