Chenliang Li 2a215410cf io_uring/rsrc: fix incorrect assignment of iter->nr_segs in io_import_fixed 
[ Upstream commit a23800f08a ]

In io_import_fixed when advancing the iter within the first bvec, the
iter->nr_segs is set to bvec->bv_len. nr_segs should be the number of
bvecs, plus we don't need to adjust it here, so just remove it.
