btrfs: remove duplicate error check at btrfs_clear_extent_bit_changeset()

Browse Source 
There's no need to check if split_state() returned an error twice, instead
unify into a single if statement after setting 'prealloc' to NULL, because
on error split_state() frees the 'prealloc' extent state record.
