[PATCH 4.9 042/102] 9p/rdma: remove useless check in cm_event_handler

[Greg Kroah-Hartman]

[ Upstream commit 473c7dd1d7b59ff8f88a5154737e3eac78a96e5b ]

the client c is always dereferenced to get the rdma struct, so c has to
be a valid pointer at this point.
Gcc would optimize that away but let's make coverity happy...
