[PATCH] alloc_tag: Use %pe format specifier

[zeng_chi911]

From: Zeng Chi <zengchi@xxxxxxxxxx>

The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR();

This patch fixes this cocci report:
lib/alloc_tag.c:776:63-70: WARNING: Consider using %pe to print PTR_ERR()
