[PATCH rdma-next 1/2] RDMA/uverbs: Remove redundant assignments

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@mellanox.com>

The kbuild reported the following warning, so clean whole uverbs_cmd.c file.

   drivers/infiniband/core/uverbs_cmd.c:1066:6: warning: Variable 'ret'
is reassigned a value before the old one has
been used. [redundantAssignment]
    ret = uverbs_request(attrs, &cmd, sizeof(cmd));
        ^
   drivers/infiniband/core/uverbs_cmd.c:1064:0: note: Variable 'ret' is
reassigned a value before the old one has been
used.
    int    ret = -EINVAL;
   ^
