ck_swlock: We shouldn't decrement n_readers when
...
ck_swlock_read_latchlocks observers a writer if the unlatch
operation sets n_readers to 0.
The unlatch operation now just unsets the latch bit, we can safely
decrement n_readers in ck_swlock_read_latchlocks().
+ Fixes to validation tests & ELIDE coverage.

for single writer workloads.
