bnxt_re: Fix memory leak in FRMR path
 
This patch fixes a memory leak issue when alloc_mr is used.
mr->pages and mr->npages are used only in alloc_mr path. mr->pages
is allocated when alloc_mr is called or in the case of FRMR, while
creating the MR. mr->npages is updated only when the MR created
is used i.e. after invoking map_mr_sg verb, before data transfer.
In the dereg_mr path, if mr->npages is 0, driver ends up not freeing
the memory created.
Removing the npages check from the dereg_mr path for kernel consumers.
