vfs: separate FMODE_PREAD/FMODE_PWRITE into separate flags
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.
