btrfs: introduce btrfs_inode_lock()/unlock()
btrfs_inode_lock/unlock() are wrappers around inode locks, separating
the type of lock and actual locking.
- 0 - default, exclusive lock
- BTRFS_ILOCK_SHARED - for shared locks, for possible parallel DIO
- BTRFS_ILOCK_TRY - for the RWF_NOWAIT sequence
The bits SHARED and TRY can be combined together.
