Subject[PATCH] rds: Remove redundant assignment to nr_sig
Date
Variable nr_sig is being assigned a value however the assignment is
never read, so this redundant assignment can be removed.

Cleans up the following clang-analyzer warning:

net/rds/ib_send.c:297:2: warning: Value stored to 'nr_sig' is never read
[clang-analyzer-deadcode.DeadStores].
