701b1f8168 Fix zvol deadlock
It's possible for a zvol_write thread to enter direct memory reclaim
while holding open a transaction group.  This results in the system
attempting to write out data to the disk to free memory.  Unfortunately,
this can't succeed because the the thread doing reclaim is holding open
the txg which must be closed to be synced to disk.  To prevent this
the offending allocation is marked KM_PUSHPAGE which will prevent it
from attempting writeback.

Closes #191

d6320ddb78 Fix gcc c90 compliance warnings
Fix non-c90 compliant code, for the most part these changes
simply deal with where a particular variable is declared.
Under c90 it must alway be done at the very start of a block.
