If prepare_write or commit_write return AOP_TRUNCATED_PAGE we jump to "retry"
label and than if find_or_create_page() failed function return incorrect error
code. Initilally i've add this fix as a part of prepare_write_retval patch,
but IMHO it is better to split this to separate fix.
Patch against 2.6.20-rc6-mm3.
