[PATCH] panic: remove the unneeded panic_print_get()

[PATCH] panic: remove the unneeded panic_print_get()

[Feng Tang]

panic_print_get() was introduced in commit 2683df6539cb ("panic: add
note that 'panic_print' parameter is deprecated") to print out warning
message of the deprecation of 'panic_print' on read access.

Since commit 90f3c123247e ("panic: only warn about deprecated panic_print
on write access"), panic_print_get() wrapper is not needed anymore for
read access, so remove it and use param_get_ulong() instead.

could you say that this is only a cleanup?

Ack.
