Pavel Labath 4cf866ce04 MemoryBuffer: Add a missing error-check to getOpenFileImpl 
Summary:
In case the function was called with a desired read size *and* the file
was not an "mmap()" candidate, the function was falling back to a
"pread()", but it was failing to check the result of that system call.
This meant that the function would return "success" even though the read
operation failed, and it returned a buffer full of uninitialized memory.
