[PATCH] nfs: flexfilelayout: fix unused-but-set variable 'err'

[Kenner de Azevedo dos Santos Miranda]

The variable int err in f_layout_io_track_ds_error() is set but not used in the code.

The warning was identified by running make w=1:

   warning: variable ‘err’ set but not used

I set the (void)err to prevent the warning.

I didn`t test with hardware, i ran again the make w=1 and the warning was removed.
