When inserting a new mmap entry to the xarray we should check for
'mmap_page' overflow as it is limited to 32 bits.

Like all other destroy commands, .destroy_cq() call is not supposed
to fail. In all flows, the attempt to return earlier caused to memory
leaks.
This patch converts .destroy_cq() to do not return any errors.

When creating the chunks list the rdma_for_each_block() iterator is used
in order to iterate over the payload in EFA_CHUNK_PAYLOAD_SIZE (device
defined) strides.

Use kvzalloc which attempts to allocate a physically continuous buffer and
fallbacks to virtually continuous on failure instead of open coding it in
the driver.
The is_vmalloc_addr function is used to determine whether the buffer is
physically continuous or not (which determines direct vs indirect MR
registration mode).

MAYEXEC test was mistakenly added, remove it. Checking MAYEXEC in the
driver prevents it from working with userspace that uses things like EXEC
STACK. (ie some Fortran and other runtimes)

Drivers cannot check the udata for validity when doing destroy as there
will be no way to report this error back to the uverbs.
Since udata is new for destroy no driver should start to use it - instead
drivers should opt for the ioctl interface and define it in a way where it
cannot fail due to incorrect data.
Remove the checks on udata construction so EFA is consistent with
everything else.
