xfs: refactor xfs_icache_free_{eof,cow}blocks call sites
In anticipation of more restructuring of the eof/cowblocks gc code, refactor calling of those two functions into a single internal helper function, then present a new standard interface to purge speculative block preallocations and start shifting higher level code to use that.
