Fix an assert in SkBmpCodec::ReadHeader

Bug: chromium:897389

The comment seems to imply that infoBytesRemaining should be at least 52
(inclusive). This matches the code below (we read 4 bytes starting at
offset 48). In addition, since this must be one of
kInfoV3_BmpHeaderType, kInfoV4_BmpHeaderType, or kInfoV5_BmpHeaderType,
It is valid for infoBytesRemaining to be 52 (and no less).
