Subject: [PATCH 1/2, resend] sunrpc/cache.h: fix coding style

Neaten code style in get_int().
Also use sizeof() instead of hard coded number as suggested by
Joe Perches <[email protected]>.

(By the way, one advantage which simple_str* does have is documentation.
Some kerneldoc comments might be helpful for kstrto* as well?)

Subject: [PATCH 2/2,resend] sunrpc/cache.h: replace simple_strtoul

This patch replaces the usage of simple_strtoul with kstrtoint in
get_int(), since the simple_str* family doesn't account for overflow
and is deprecated.
Also, in this specific case, the long from strtol is silently converted
to an int by the caller.

As Joe Perches <[email protected]> suggested, this patch also removes
the redundant temporary variable rv, since kstrtoint() will not write to
anint unless it's successful.
