locktorture: Add acq_writer_lim to complain about long acquistion times
This commit adds a locktorture.acq_writer_lim module parameter that
specifies the maximum number of jiffies that is expected to be consumed
by write-side lock acquisition. If this limit is exceeded, a WARN_ONCE()
causes a splat. Note that this limit applies to the main lock acquisition
only, not to any nested acquisitions.
