ext4: remove an unused variable warning with CONFIG_QUOTA=n

Browse source 
[ Upstream commit 3bbef91bdd ]

The 'enable_quota' variable is only used in an CONFIG_QUOTA.
With CONFIG_QUOTA=n, compiler causes a harmless warning:

fs/ext4/super.c: In function ‘ext4_remount’:
fs/ext4/super.c:5840:6: warning: variable ‘enable_quota’ set but not used
  [-Wunused-but-set-variable]
  int enable_quota = 0;
              ^~~~~

Move 'enable_quota' into the same #ifdef CONFIG_QUOTA block
to remove an unused variable warning.
