RDMA/bnxt_re: Fix OOB write in bnxt_re_copy_err_stats()

In the Linux kernel, the following vulnerability has been resolved:

RDMA/bnxt_re: Fix OOB write in bnxt_re_copy_err_stats()

Commit ef56081d1864 ("RDMA/bnxt_re: RoCE related hardware counters
update") added three new counters and placed them after
BNXT_RE_OUT_OF_SEQ_ERR.

BNXT_RE_OUT_OF_SEQ_ERR acts as a boundary marker for allocating hardware
statistics with different num_counters values on chip_gen_p5_p7 devices.

As a result, BNXT_RE_NUM_STD_COUNTERS are used when allocating
hw_stats, which leads to an out-of-bounds write in
bnxt_re_copy_err_stats().

The counters BNXT_RE_REQ_CQE_ERROR, BNXT_RE_RESP_CQE_ERROR, and
BNXT_RE_RESP_REMOTE_ACCESS_ERRS are applicable to generic hardware, not
only p5/p7 devices.

Fix this by moving these counters before BNXT_RE_OUT_OF_SEQ_ERR so they
are included in the generic counter set.
