Subject: RDMA/rtrs: Remove len parameter from helper print functions of sysfs
Patch-mainline: v5.16-rc1
Git-commit: 80ad07f7e2bfab79e6209c7b8ce4665ffd9f25ed
References: jsc#SLE-19249

Since we have changed all sysfs show functions to use sysfs_emit, we do
not require the len (PAGE_SIZE) in our helper print functions. So remove
it from the function parameter.
