[WebAudio] Ensure AudioBufferSourceNode doesn't read past the input source
when not looping
https://bugs.webkit.org/show_bug.cgi?id=287477
Reviewed by Darin Adler and Chris Dumez.
Add an early exit from AudioBufferSourceNode::renderFromBuffer()
instead of reading past the source buffer when m_isLooping is false.
The read cursor in AudioBufferSourceNode may have been set e.g. due to a
previous ::renderFromBuffer() call to a position past the end of the
source buffer. If the node has m_isLooping set the existing checks will
reset the cursor to the beginning of the loop; but if not looping then
we may attempt to read past the end of the source buffer.
