IB/qib: Correct nfreectxts for multiple HCAs
The code that was recently introduced to report the number
of free contexts is flawed for multiple HCAs:
/* Return the number of free user ports (contexts) available. */
return scnprintf(buf, PAGE_SIZE, "%u\n", dd->cfgctxts -
dd->first_user_ctxt - (u32)qib_stats.sps_ctxts);
The qib_stats is global to the module, not per HCA, so the code is broken
for multiple HCAs.
This patch adds a qib_devdata field, freectxts, that reflects the free
contexts for this HCA.
