btrfs: remove the pg_offset parameter from btrfs_get_extent()
The parameter @pg_offset of btrfs_get_extent() is only utilized for
inlined extent, and we already have an ASSERT() and tree-checker, to
make sure we can only get inline extent at file offset 0.
Any invalid inline extent with non-zero file offset would be rejected by
tree-checker in the first place.
Thus the @pg_offset parameter is not really necessary, just remove it.
