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 #2)
- 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].
