Subject: [PATCH] sh: kernel: hw_breakpoint: Fix missing break in switch statement

Add missing break statement in order to prevent the code from
erroneously falling through to case SH_BREAKPOINT_WRITE.

Fixes: 09a072947791 ("sh: hw-breakpoints: Add preliminary support for SH-4A UBC.")

If no one cares, I'll apply this to my tree and queue it up for 5.3-rc4.
