Currently we're passing -1 to truncate_inode_pages_range() which is
actually really confusing since the argument is signed so we do not get
"huge" number as one would expect, but rather just -1. To make things
clearer and easier for truncate_inode_pages_range() just pass LLONG_MAX
since it is actually what was intended anyway.
It also makes thing easier for allowing truncate_inode_pages_range() to
handle non page aligned regions. Moreover letting the lend argument to
be negative might actually hide some bugs.
