IB/core: Make testing MR flags for writability a static inline function
commit 08bb558ac11ab944e0539e78619d7b4c356278bd upstream.
Make the MR writability flags check, which is performed in umem.c,
a static inline function in file ib_verbs.h
This allows the function to be used by low-level infiniband drivers.
