Ricardo M. Correia 4ca4dfe9bb Fix taskq_dispatch() call in zio_taskq_dispatch(). 
The feature branch 'fix-taskq' in Linux's ZFS tree changes the taskq_dispatch()
flag from TQ_SLEEP to TQ_NOSLEEP to avoid sleeping in some circumstances.

However, this has the side effect that taskq_dispatch() now may fail, and since
the return code was not even being checked, it could lead to zio's not being
scheduled to execute.

I'm fixing this in a simplistic but not very elegant way, by just looping until
taskq_dispatch() succeeds.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!

Documentation for building, configuring, and using ZFS can be found at: http://wiki.github.com/behlendorf/zfs/
