Trond Myklebust 469ce5119f NFS: Use of mapping_set_error() results in spurious errors ...

[ Upstream commit 6c984083ec2453dfd3fcf98f392f34500c73e3f2 ]

The use of mapping_set_error() in conjunction with calls to
filemap_check_errors() is problematic because every error gets reported
as either an EIO or an ENOSPC by filemap_check_errors() in functions
such as filemap_write_and_wait() or filemap_write_and_wait_range().
In almost all cases, we prefer to use the more nuanced wb errors.
