net: ethtool: Add default branch to sff8636_show_all_ioctl switch

The current sff8636_show_all_ioctl code uses a switch statement
to determine the module type, and exits directly with a return statement
when a match is found. However, when the module type cannot be matched,
the sff8636_memory_map_init_buf and sff8636_show_all_common functions
are executed. This writing style is not intuitive enough.
Therefore, this patch adding a default branch in the switch statement
to improve the readability of the code.
