btrfs: don't BUG_ON btrfs_alloc_path() errors
This patch fixes many callers of btrfs_alloc_path() which BUG_ON allocation failure. All the sites that are fixed in this patch were checked by me to be fairly trivial to fix because of at least one of two criteria: - Callers of the function catch errors from it already so bubbling the error up will be handled. - Callers of the function might BUG_ON any nonzero return code in which case there is no behavior changed (but we still got to remove a BUG_ON) The following functions were updated: btrfs_lookup_extent, alloc_reserved_tree_block, btrfs_remove_block_group, btrfs_lookup_csums_range, btrfs_csum_file_blocks, btrfs_mark_extent_written, btrfs_inode_by_name, btrfs_new_inode, btrfs_symlink, insert_reserved_file_extent, and run_delalloc_nocow Signed-off-by: Mark Fasheh <mfasheh@suse.com>
