Brian Behlendorf d958324f97 Fix zfs_putpage() lock inversion (again) 
This is a follow up commit to 74328ee which correctly resolved a lock
inversion between zfs_putpage() and zfs_free_range().  Unfortunately,
in the process it accidentally introduced another inversion between
zfs_putpage() and zfs_read().  The page must be unlocked before taking
the range lock.  This patch corrects that issue.

In addition, because the locking rules here are subtle a block comment
has been added clearly explaining why the ordering here is critical.
