vfs: separate FMODE_PREAD/FMODE_PWRITE into separate flags

commit 55ec82176eca52e4e0530a82a0eb59160a1a95a1 upstream.

Separate FMODE_PREAD and FMODE_PWRITE into separate flags to reflect the
reality that the read and write paths may have independent restrictions.

A git grep verifies that these flags are always cleared together so this
new behavior will only apply to interfaces that change to clear flags
individually.

This is required for "seq_file: properly cope with pread", a post-2.6.25
regression fix.
