[PATCH] Staging: nvec: Change container_of macro to an inline function.

[Sumitra Sharma]

The macro has the drawback that one cannot determine
what type it applies to by looking at the definition.
Hence this macro definition is not type-safe.

The inline function gives the same benefits as the
macro and only accepts the specific type of arguments.
Use static because the definition only requires it to be
visible in the current file.
