7a5834e456 RDMA/efa: Handle mmap insertions overflow
When inserting a new mmap entry to the xarray we should check for
'mmap_page' overflow as it is limited to 32 bits.

4f240dfec6 RDMA/efa: Remove MAYEXEC flag check from mmap flow
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)
