Liam Howlett 58ee5a0de1 m68k: Add missing mmap_read_lock() to sys_cacheflush() ...

[ Upstream commit f829b4b212 ]

When the superuser flushes the entire cache, the mmap_read_lock() is not
taken, but mmap_read_unlock() is called.  Add the missing
mmap_read_lock() call.

Fixes: cd2567b685 ("m68k: call find_vma with the mmap_sem held in sys_cacheflush()")
