This patch prevents division by zero, when
source_get_frame_bytes() routine returns 0.
This change fixes issue https://github.com/thesofproject/sof/issues/8414.
The problem happens due to race condition during pipeline pause operation.
The exact failure mechanism require additional debug, but checking
frame_bytes value before division prevents exceptions.
