Since fscrypt users can now indicated if fscrypt_encrypt_page() should
use a bounce page, we can delay the bounce page pool initialization util
it is really needed. That is until fscrypt_operations has no
FS_CFLG_OWN_PAGES flag set.

In case of in-place encryption fscrypt_ctx was allocated but never
released. Since we don't need it for in-place encryption, we skip
allocating it.

Rename the FS_CFLG_INPLACE_ENCRYPTION flag to FS_CFLG_OWN_PAGES which,
when set, indicates that the fs uses pages under its own control as
opposed to writeback pages which require locking and a bounce buffer for
encryption.

Actually use the fs-provided index instead of always using page->index
which is only set for page-cache pages.

A customer hit a crash where the napi sd->poll_list became corrupted.
The customer had the bnx2x driver, which does a

running with CONFIG_PREEMPT_RT_FULL, this interrupt handler is run as a
