Further cleanups to enable_flash_cs5536

Browse Source 
- Remove the "enable write to flash" message, as the caller appears to
   already report that.

 - Move the 'modprobe msr' suggestions to the first lseek64 error handling, as
   we get an error there already.

 - Rename a perror string from "read" to "read msr", as we use the latter
   already in this function for another read.

Corresponding to flashrom svn r195 and coreboot v2 svn r3101.
