[PATCH v3 1/2] NFS: remove redundant __private attribute from nfs_page_class

[Sean Chang <seanwascoding@gmail.com>]

The nfs_page_class tracepoint uses a pointer for the 'req' field marked
with the __private attribute. This causes Sparse to complain about
dereferencing a private pointer within the trace ring buffer context,
specifically during the TP_fast_assign() operation.

This fixes a Sparse warning introduced in commit b6ef079fd984 ("nfs:
more in-depth tracing of writepage events") by removing the redundant
__private attribute from the 'req' field.
