[PATCH] staging: most: dim2: remove unnecessary NULL check in try_start_dim_transfer()

[grondon]

From: Gabriel Rondon <grondon@gmail.com>

Remove the !hdm_ch check. Although hdm_ch is a function parameter,
it is already dereferenced on the preceding line to initialize
head (head = &hdm_ch->pending_list), so a NULL check after that
point is dead code.
