ext4: correct the cache_nr in tracepoint ext4_es_shrink_exit



The cache_cnt parameter of tracepoint ext4_es_shrink_exit means the
remaining cache count after shrink, but now it is the cache count before
shrink, fix it by read sbi->s_extent_cache_cnt again.

Fixes: 1ab6c499 ("fs: convert fs shrinkers to new scan/count API")
