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].
