Subject: [PATCH v2 14/52] m68k: emu: Remove unused vsnprintf() return value in nfprint()

When building with W=1:

    arch/m68k/emu/natfeat.c: In function ‘nfprint’:
    arch/m68k/emu/natfeat.c:59:13: warning: variable ‘n’ set but not used [-Wunused-but-set-variable]
       59 |         int n;
	  |             ^

As the return value of vsnprintf() is unused, and serves no practical
purpose here, fix this by removing the variable.
