Description
Just noticed on 3.0.2/x86_64 that there is at least one 32/64 problem
in msdosfs:

&& !bcmp(fp->fsisig3, "\0\0\125\252", 4)
&& !bcmp(fp->fsisig4, "\0\0\125\252", 4)) {
pmp->pm_nxtfree = getulong(fp->fsinxtfree);
- if (pmp->pm_nxtfree 0xffffffff)
if (pmp->pm_nxtfree (u_long)-1)
pmp->pm_nxtfree = CLUST_FIRST;
} else
pmp->pm_fsinfo = 0;
Without this change I get "Next free cluster in FSInfo
(18446744073709551615) exceeds maxcluster (244833)" when I try to
mount a 8GB SDHC card on x86_64.

Confirmed with an 8GB filesystem locally; patch committed to master. (68cc29492751172e9897a90c303b1c7fbb18112a)
Should be MFC-ed.
