[PATCH -next] afs: Remove unused variable in afs_req_issue_op()

[Wei Yongjun]

GCC reports the following warning with W=1:

fs/afs/file.c:291:6: warning:
 unused variable 'ret' [-Wunused-variable]
  291 |  int ret;
      |      ^~~

After commit 799fbdf96cd51, this variable is not used in function
afs_req_issue_op(), so this commit remove it to fix the warning.

Fixes: 799fbdf96cd51 ("afs: Use new fscache read helper API")
