resvtest.c: fix invalid use of sizeof()

sizeof(pointer) will give you the size of a pointer, not the space
allocated to it.  I noticed this when gcc complained:

resvtest.c:76:33: warning: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to provide an explicit length? [-Wsizeof-pointer-memaccess]
  memset(writebuffer, 'A', sizeof(writebuffer));
