fs/minix: set s_maxbytes correctly

BugLink: https://bugs.launchpad.net/bugs/1892899
[ Upstream commit 32ac86efff91a3e4ef8c3d1cadd4559e23c8e73a ]

The minix filesystem leaves super_block::s_maxbytes at MAX_NON_LFS rather
than setting it to the actual filesystem-specific limit.  This is broken
because it means userspace doesn't see the standard behavior like getting
EFBIG and SIGXFSZ when exceeding the maximum file size.

Fix this by setting s_maxbytes correctly.
