esx: reorder code to avoid need to VIR_FREE mimeType

mimeType is initialized to NULL, and then only set in one place, just
before a check (not involving mimeType) that then VIR_FREEs mimeType
if it fails. If we just reorder the code to do the check prior to
setting mimeType, then there won't be any need to VIR_FREE(mimeType)
on failure (because it will already be empty/NULL).
