uaccess: Fix scoped_user_read_access() for 'pointer to const'
If a 'const struct foo __user *ptr' is used for the address passed to
scoped_user_read_access() then you get a warning/error
uaccess.h:691:1: error: initialization discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
for the
void __user *_tmpptr = __scoped_user_access_begin(mode, uptr, size, elbl)
assignment.
Fix by using 'auto' for both _tmpptr and the redeclaration of uptr.
Replace the CLASS() with explicit __cleanup() functions on uptr.
Fixes: e497310b4ffb ("uaccess: Provide scoped user access regions")
