switch generic_write_checks() to iocb and iter
... returning -E... upon error and amount of data left in iter after (possible) truncation upon success. Note, that normal case gives a non-zero (positive) return value, so any tests for != 0 _must_ be updated. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Conflicts: fs/ext4/file.c
