make new_sync_{read,write}() static

Browse Source 
All places outside of core VFS that checked ->read and ->write for being NULL or
called the methods directly are gone now, so NULL {read,write} with non-NULL
{read,write}_iter will do the right thing in all cases.

[mandatory]
f_dentry is gone; use f_path.dentry, or, better yet, see if you can avoid
it entirely.
--
[mandatory]
never call ->read() and ->write() directly; use __vfs_{read,write} or
wrappers; instead of checking for ->write or ->read being NULL, look for
FMODE_CAN_{WRITE,READ} in file->f_mode.
--
[mandatory]
do _not_ use new_sync_{read,write} for ->read/->write; leave it NULL
instead.
