[PATCH v2 11/13] staging/rdma/hfi1: Remove unneeded variable index

[Jubin John <jubin.john@xxxxxxxxx>]

From: Dean Luick <dean.luick@xxxxxxxxx>

The variable "index" increments the same as dd->ndevcntrs.
Just use the later.  Remove uneeded usage of "index" in the
fill loop - it is not used there or later in the function.
