Brian Behlendorf 3050c9314f Switch KM_SLEEP to KM_PUSHPAGE ...

Under certain circumstances the following functions may be called
in a context where KM_SLEEP is unsafe and can result in a deadlocked
system.  To avoid this problem the unconditional KM_SLEEPs are
converted to KM_PUSHPAGEs.  This will prevent them from attempting
to initiate any I/O during direct reclaim.

This change was originally part of cd5ca4b but was reverted by
330fe01.  It always should have had its own commit for exactly
this reason.
