staging: rtl8723bs: remove unnecessary else after break

This patch fixes the checkpatch.pl warning:
"WARNING: else is not generally useful after a break or return"

In sdio_ops_linux.c, the else blocks after break statements are
redundant. Removing them reduces indentation level and improves
code readability.
