Jingbo Xu 0955b8eac3 erofs: fix potential overflow calculating xattr_isize ...

[ Upstream commit 1b3567a1969b26f709d82a874498c0754ea841c3 ]

Given on-disk i_xattr_icount is 16 bits and xattr_isize is calculated
from i_xattr_icount multiplying 4, xattr_isize has a theoretical maximum
of 256K (64K * 4).

Thus declare xattr_isize as unsigned int to avoid the potential overflow.
