[PATCH] IB/mthca: Fix FMR breakage caused by kmemdup() conversion
Commit bed8bdfd ("IB: kmemdup() cleanup") introduced one bad conversion to
kmemdup() in mthca_alloc_fmr(), where the structure allocated and the
structure copied are not the same size. Revert this back to the original
kmalloc()/memcpy() code.
