kallsyms: make kallsyms_show_value() as generic function
This change makes function kallsyms_show_value() as
generic function without dependency on CONFIG_KALLSYMS.
Now module address will be displayed with lsmod and /proc/modules.
Earlier:
=======
/ # insmod test.ko
/ # lsmod
test 12288 0 - Live 0x0000000000000000 (O) // No Module Load address
/ #
With change:
==========
/ # insmod test.ko
/ # lsmod
test 12288 0 - Live 0xffff800000fc0000 (O) // Module address
/ # cat /proc/modules
test 12288 0 - Live 0xffff800000fc0000 (O)
