[PATCH] infiniband: remove unnecessary fallthrough usage

From: Cengiz Can
Date: Mon Aug 31 2020 - 11:31:36 EST


Since /* fallthrough */ comments are deprecated[1], they are being replaced
by new 'fallthrough' pseudo-keyword.

[1] https://www.kernel.org/doc/html/v5.7/process/deprecated.html?\
highlight=fallthrough#implicit-switch-case-fall-through

This sometimes leads to unreachable code warnings by static analyzers,
particularly in this case, Coverity Scanner. (CID 1466512)

Remove unnecessary 'fallthrough' keywords to prevent dead code
warnings.
