Filipe Manana 1e96847362 btrfs: use u64 for buffer sizes in the tree search ioctls 
[ Upstream commit dec96fc2dcb59723e041416b8dc53e011b4bfc2e ]

In the tree search v2 ioctl we use the type size_t, which is an unsigned
long, to track the buffer size in the local variable 'buf_size'. An
unsigned long is 32 bits wide on a 32 bits architecture. The buffer size
defined in struct btrfs_ioctl_search_args_v2 is a u64, so when we later
try to copy the local variable 'buf_size' to the argument struct, when
the search returns -EOVERFLOW, we copy only 32 bits which will be a
problem on big endian systems.

Fix this by using a u64 type for the buffer sizes, not only at
btrfs_ioctl_tree_search_v2(), but also everywhere down the call chain
so that we can use the u64 at btrfs_ioctl_tree_search_v2().

Fixes: cc68a8a5a433 ("btrfs: new ioctl TREE_SEARCH_V2")
