btrfs: make the logic from btrfs_block_can_be_shared() easier to read

The logic in btrfs_block_can_be_shared() is hard to follow as we have a
lot of conditions in a single if statement including a subexpression with
a logical or and two nested if statements inside the main if statement.

Make this easier to read by using separate if statements that return
immediately when we find a condition that determines if a block can be
or can not be shared.
