[PATCH] fs/proc: avoid unused ctl_table entry in init_header

[Safety 1 <git.userk@gmail.com>]

The entry variable in init_header() is only used by
list_for_each_table_entry() for iteration and is never read. With
-Werror=unused-but-set-variable, this causes the build to fail.

Use the table size directly for the loop since the entry value is
not needed here.

Tested with: make -j$(nproc)
