msgb: Assert len >= 0 in msgb_trim

Currently msgb_trim only checks for len > data_len and returns -1
in that case, allowing the caller to fix it somehow. Using a negative
length will always lead to a corrupt msgb, but this is not being
checked.

This commit adds a check for len < 0 and a conditional call to MSGB_ABORT.
