David Howells 4090b31422 netfs: Add a function to consolidate beginning a read 
Add a function to do the steps needed to begin a read request, allowing
this code to be removed from several other functions and consolidated.

Changes
=======
ver )
 - Move before the unstaticking patch so that some functions can be left
   static.
 - Set uninitialised return code in netfs_begin_read()[1][2].
 - Fixed a refleak caused by non-removal of a get from netfs_write_begin()
   when the request submission code got moved to netfs_begin_read().
 - Use INIT_WORK() to (re-)init the request work_struct[3].
