[ Upstream commit 1216e9ef18b84f4fb5934792368fb01eb3540520 ]
Building with W=1 enables the compiler warning -Wimplicit-fallthrough=3. That option does not recognize the fall-through comment in the fcloop driver. Add a fall-through comment that is recognized for -Wimplicit-fallthrough=3. This patch avoids that the compiler reports the following warning when building with W=1:
drivers/nvme/target/fcloop.c:647:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (op == NVMET_FCOP_READDATA) ^
