staging: axis-fifo: Fix kernel-doc return value warnings

The kernel-doc comments for axis_fifo_read() and axis_fifo_write()
describe their return values as free text, which kernel-doc does not
recognize as a return section:

  $ scripts/kernel-doc -Wall -none drivers/staging/axis-fifo/axis-fifo.c
  Warning: drivers/staging/axis-fifo/axis-fifo.c:121 No description
  found for return value of 'axis_fifo_read'
  Warning: drivers/staging/axis-fifo/axis-fifo.c:214 No description
  found for return value of 'axis_fifo_write'

These warnings only show up in a direct kernel-doc invocation or a
W=2 build (-Wall is added to kernel-doc only when KBUILD_EXTRA_WARN
contains 2), which is why W=1 builds appear clean.

Convert the trailing "Returns ..." sentences into Return: sections so
kernel-doc recognizes the existing return value documentation. No
functional change.
