[PATCH v6 05/37] fs: Convert alloc_inode_sb() to a macro

From: Suren Baghdasaryan

From: Kent Overstreet <kent.overstreet@xxxxxxxxx>

We're introducing alloc tagging, which tracks memory allocations by
callsite. Converting alloc_inode_sb() to a macro means allocations will
be tracked by its caller, which is a bit more useful.
