Fix PR 93242: patchable-function-entry broken on MIPS

On MIPS, .set noreorder/reorder needs to emitted around
the nop.  The template for the nop instruction uses %(/%) to
do that.  But default_print_patchable_function_entry uses
fprintf rather than output_asm_insn to output the instruction.

This fixes the problem by using output_asm_insn to emit the nop
instruction.

ChangeLog:

* targhooks.c (default_print_patchable_function_entry): Use
output_asm_insn to emit the nop instruction.
