Source kernel commit: 0b3a76e955ebe3d71a2bcd5990404ed522b40e17

When running in a transaction context, memory allocations are scoped
to GFP_NOFS. Hence we don't need to use GFP_NOFS contexts in pure
transaction context allocations - GFP_KERNEL will automatically get
converted to GFP_NOFS as appropriate.

Go through the code and convert all the obvious GFP_NOFS allocations
in transaction context to use GFP_KERNEL. This further reduces the
explicit use of GFP_NOFS in XFS.
