Subject: [PATCH 4.20 151/171] iscsi_ibft: Fix missing break in switch statement

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gustavo A. R. Silva <gustavo@...eddedor.com>

commit df997abeebadaa4824271009e2d2b526a70a11cb upstream.

Add missing break statement in order to prevent the code from falling
through to case ISCSI_BOOT_TGT_NAME, which is unnecessary.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.
