xprtrdma: Fix XDRBUF_SPARSE_PAGES support ...
commit 15261b9126cd5bb2ad8521da49d8f5c042d904c7 upstream.
Olga K. observed that rpcrdma_marsh_req() allocates sparse pages
only when it has determined that a Reply chunk is necessary. There
are plenty of cases where no Reply chunk is needed, but the
XDRBUF_SPARSE_PAGES flag is set. The result would be a crash in
rpcrdma_inline_fixup() when it tries to copy parts of the received
Reply into a missing page.
To avoid crashing, handle sparse page allocation up front.
Until XATTR support was added, this issue did not appear often
because the only SPARSE_PAGES consumer always expected a reply large
enough to always require a Reply chunk.
