ubi: ubi_get_ec_info: Fix compiling error 'cast specifies array type'
On risc V platform, there is a type conversion for the return value
(unsigned long type) of __untagged_addr_remote() in function
untagged_addr(). The compiler will complain when the parameter 'addr'
is an array type:
arch/riscv/include/asm/uaccess.h:33:9: error: cast specifies array type
(__force __typeof__(addr))__untagged_addr_remote(current->mm, __addr)
Fix it by converting the input parameter as a pointer.
