This pre-patch helps make the next libxfs-sync for 5.11 a bit
more clear.

In reality, the libxfs_inode_alloc function matches the kernel's
xfs_dir_ialloc so rename it for clarity before the rest of the
sync, and change several variable names for the same reason.

The subsequent uses of tp no longer refer to the right transaction after
this roll. FWIW, there is a subtle difference with the kernel code where
this call passes &tp and then updates tpp on return, but we could also
just update tp here if that's still good enough to facilitate the libxfs
sync.

Whoops, now I remember meaning to go back and check that, thanks, I'll
take a closer look.
