[PATCH] Remove 'strchr' warning from reiserfs

[Sam Ravnborg <sam@ravnborg.org>]

Hi Linus, please apply - maintainer cc:ed for info.

Reiserfs emits a warning about strchr being defined but not
used. I finally tracked down the reason for this.
gcc - when seeing strstr(x, "%") recognized that the second parameter
is a char, and therefore uses strchr instead of strstr.
The workaround to avoid the warning is to replace the call
to strstr with strchr - which is OK.

This hides the warning, and brings us down to 6 warnings for a
make defconfig bzImage.
