btrfs: reduce nesting for extent processing at btrfs_lookup_extent_info()

Browse source

Instead of using an if-else statement when processing the extent item at
btrfs_lookup_extent_info(), use a single if statement for the error case
since it does a goto at the end and leave the success (expected) case
following the if statement, reducing indentation and making the logic a
bit easier to follow. Also make the if statement's condition as unlikely
since it's not expected to ever happen, as it signals some corruption,
making it clear and hint the compiler to generate more efficient code.
