ext3: Properly count journal credits for long symlinks
Commit ae54870a1dc9 ("ext3: Fix lock inversion in ext3_symlink()")
recalculated the number of credits needed for a long symlink, in the
process of splitting it into two transactions. However, the first
credit calculation under-counted because if selinux is enabled, credits
are needed to create the selinux xattr as well.
Overrunning the reservation will result in an OOPS in
journal_dirty_metadata() due to this assert:
J_ASSERT_JH(jh, handle->h_buffer_credits > 0);
Fix this by increasing the reservation size.
