[PATCH 43/47] staging/lustre/osc: Update inode timestamp for lockless IO as well

[Oleg Drokin <green@linuxhacker.ru>]

From: Swapnil Pimpale <spimpale@ddn.com>

Removed the checks for oi_lockless from osc_io_read_start() and
osc_io_write_start(). This patch also removes the unnecessary call to
cl_object_attr_get() in osc_io_write_start() before calling
cl_object_attr_set()
