Alan Somers eced2e2f1e libzfs: Fix mounting datasets under thread limit pressure
During parallel zpool import, /sbin/zpool will create a separate thread
pool for each pool, used to mount that pool's datasets.  If the total
thread count exceed's the system's limit on threads per process, then
tpool_dispatch may fail.  If it does, directly execute the mount
operation instead.
