xfs: make xfs_inode_set_eofblocks_tag cheaper for the common case
For long growing file writes we will usually already have the
eofblocks tag set when adding more speculative preallocations. Add
a flag in the inode to allow us to skip the the fairly expensive
AG-wide spinlocks and multiple radix tree operations in that case.
