Since progress entries array is globally allocated, it is susceptible to race conditions when using multi-threaded applications. Allocating it on the stack resolves any potential races as it is thread local by default.

(cherry picked from commit ed23430)
Conflicts:
ompi/mca/mtl/ofi/mtl_ofi_component.c
ompi/mca/mtl/ofi/mtl_ofi_types.h
Conflicts were mainly due to some features in master and not in the release branch. So git was complaining about missing lines while cherry-picking.
