Make some miscellaneous fixes to the first paragraph of "ECC memory":
 - Change the incorrect "74 bits" to "72 bits".
 - Change "mentioned on" to "mentioned in".
 - Remove the extra "extra".
 - Rephrase some sentences as suggested by Matthew Wilcox.

 ECC memory
 ----------
 
-As mentioned on the previous section, ECC memory has extra bits to be
-used for error correction. So, on 64 bit systems, a memory module
-has 64 bits of *data width*, and 74 bits of *total width*. So, there are
-8 bits extra bits to be used for the error detection and correction
-mechanisms. Those extra bits are called *syndrome*\ [#f1]_\ [#f2]_.

 So, when the cpu requests the memory controller to write a word with
 *data width*, the memory controller calculates the *syndrome* in real time,
