[PATCH] RDMA/bnxt_re: fix verbs undefined build errors

[PATCH] RDMA/bnxt_re: fix verbs undefined build errors

[Randy Dunlap]

When INFINIBAND_USER_ACCESS is not set, the bnxt_re driver has
build errors:

ERROR: modpost: "uverbs_idr_class" [drivers/infiniband/hw/bnxt_re/bnxt_re.ko] undefined!
ERROR: modpost: "ib_uverbs_get_ucontext_file" [drivers/infiniband/hw/bnxt_re/bnxt_re.ko] undefined!
ERROR: modpost: "uverbs_destroy_def_handler" [drivers/infiniband/hw/bnxt_re/bnxt_re.ko] undefined!

Handle this case by making the driver depend on INFINIBAND_USER_ACCESS.

I liked this variant [1] more as bnxt_re driver can theoretically work
without INFINIBAND_USER_ACCESS too.
