xfs: Update inode alloc comments
I found some out of date comments while studying the inode allocation code, so I believe it's worth to have these comments updated. It basically rewrites the comment regarding to "call_again" variable, which is not used anymore, but instead, callers of xfs_ialloc() decides if it needs to be called again relying only if ialloc_context is NULL or not. Also did some small changes in another comment that I thought to be pertinent to the current behaviour of these functions and some alignment on both comments.
