RDMA/hns: Fix comparison of unsigned long variable 'end' with less than zero
Currently the comparison of end with less than zero is always false
because end is an unsigned long. Also, replace checks of end with
non-zero with end > 0 as it is possible that the #defined decrement may be
changed in the future causing end to step over zero and go negative.
The initialization of end with 0 is also redundant as this value is never
read and is later set to HW_SYNC_TIMEOUT_MSECS, so fix this by
initializing it with this value to begin with.
