Michael J. Ruhl 7709b0dc26 IB/hfi1: Remove overly conservative VM_EXEC flag check 
Applications that use the stack for execution purposes cause userspace PSM
jobs to fail during mmap().

Both Fortran (non-standard format parsing) and C (callback functions
located in the stack) applications can be written such that stack
execution is required. The linker notes this via the gnu_stack ELF flag.

This causes READ_IMPLIES_EXEC to be set which forces all PROT_READ mmaps
to have PROT_EXEC for the process.

Checking for VM_EXEC bit and failing the request with EPERM is overly
conservative and will break any PSM application using executable stacks.

Cc: <stable@vger.kernel.org> #v4.14+
Fixes: 1222026764 ("IB/hfi: Protect against writable mmap")
