m68k: amiga: pcmcia: Replace set but not used variable by READ_ONCE()
When building with W=1: arch/m68k/amiga/pcmcia.c: In function ‘pcmcia_reset’: arch/m68k/amiga/pcmcia.c:29:23: warning: variable ‘b’ set but not used [-Wunused-but-set-variable] 29 | unsigned char b; | ^ Fix this by using READ_ONCE(), and removing the variable.
