Alexander Usyskin 78b98b6e56 mei: use kvmalloc for read buffer ...

[ Upstream commit 4adf613e01 ]

Read buffer is allocated according to max message size, reported by
the firmware and may reach 64K in systems with pxp client.
Contiguous 64k allocation may fail under memory pressure.
Read buffer is used as in-driver message storage and not required
to be contiguous.
Use kvmalloc to allow kernel to allocate non-contiguous memory.
